There is a long standing issue which could cause fs shutdown due to
inode extent-to-btree conversion failure right after an extent
allocation in the same AG, which is absolutely unexpected due to the
proper minleft reservation in the previous allocation. Brian once
addressed one of the root cause [1], however, such symptom can still
occur after the commit is merged as reported [2], and our cloud
environment is also suffering from this issue.
From the description of the commit [1], I found that Zirong has an
in-house stress test reproducer for this issue, therefore I asked him
to reproduce again and he confirmed that such issue can still be
reproduced on RHEL 9 in several days.
Thanks to him, after adding some debugging code to dump the current
transaction log items, I think the root cause is as below:
1. xfs_bmapi_allocate() with the following condition:
freeblks: 18304 pagf_flcount: 6
reservation: 18276 need (min_free): 6
args->minleft: 1
available = freeblks + agflcount - reservation - need - minleft
= 18304 + min(6, 6) - 18276 - 6 - 1 = 27
The first allocation check itself is ok, and args->maxlen = 27
here
At this time, AG 3 also has the following state:
1st:64 last:69 cnt:6 longest:6395
AGFL has the following state:
64:547 65:167 66:1651 67:2040807 68:783 69:604
2. Tried to get 27 blocks from this AG, but in order to finish such
allocation, it had to need a new btree block for cntbt (so take
another free block from agfl). It can be seen with a new AGF
recorded in the transaction:
blkno 62914177, len 1, map_size 1
00000000: 58 41 47 46 00 00 00 01 00 00 00 03 00 27 ff f0 XAGF.........'..

00000040: 75 dc c1 b5 1a 45 40 2a 80 50 72 f0 59 6e 62 66 u....E@*.Pr.Ynbf
It can be parsed as:
agf 3 flfirst: 65 (0x41) fllast: 69 (0x45) cnt: 5
freeblks 18277
3. agfl 64 (agbno 547, daddr 62918552) was then written as a cntbt
block, which can also be seen in a log item as below:
type#011= 0x123c
flags#011= 0x8
blkno 62918552, len 8, map_size 1
00000000: 41 42 33 43 00 00 00 fd 00 1f 23 e4 ff ff ff ff AB3C......#.....

00000020: 75 dc c1 b5 1a 45 40 2a 80 50 72 f0 59 6e 62 66 u....E@*.Pr.Ynbf
...
4. Finally, the following inode extent to btree allocation fails
as below:
kernel: ------------[ cut here ]------------
WARNING: CPU: 15 PID: 49290 at fs/xfs/libxfs/xfs_bmap.c:717 xfs_bmap_extents_to_btree+0xc51/0x1050 [xfs]
...
XFS (sda2): agno 3 agflcount 5 freeblks 18277 reservation 18276 6
since freeblks = 18304 - 27 = 18277, but with another agfl
block allocated (pagf_flcount from 6 to 5), the inequality will
not be satisfied:
available = freeblks + agflcount - reservation - need - minleft
= 18277 + min(5, 6) - 18276 - 6 - 0 = 0 < 1
Full current transaction log item dump can be fetched from [3].
As a short-term solution, the following allocations (e.g. allocation
for inode extent-to-btree conversion) can be recorded in order to count
more blocks to reserve for safely freespace btree splits so that it
will shorten available and args->maxlen to
available = freeblks + agflcount - reservation - need - minleft
= 18304 + min(6, 6) - 18276 - 6*2 - 1 = 21
args->maxlen = 21
in the first allocation, and the following conversion should then
succeed. At least, it's easy to be backported and do hotfix.
In the long term, args->total and args->minleft have be revisited
although it could cause more refactoring.

FYI, I've tested this bug, with the original reproducer I hit this bug. Although
the reproducer is a big long time (3days) stress test, and can't reproduce
this bug 100%, but generally with about 1/5 chance.
So I submitted 6 testing jobs, all test passed today, didn't this bug, so I
think this patch works for me. (This testing can't replace regression test)
Anway, for more convince, I just submitted more 6 testing jobs again. They'll
be done on next Monday (11-14). I'll feedback if there're any problems, or
nothing wrong.
Thanks,
Zorro

That's not going to work. What happens when we do a full bno
split? Or we do both a bno and a cnt split in the same allocation?
Regardless, I don't see anything wrong with the allocation setup -
it's telling the allocation code exactly what it needs for
subsequent BMBT block allocations to succeed (i.e. args->minleft).
The problem here is that the internal allocation code is failing to
handle the corner case where space is just about gone correctly.
As I pointed out previously - we have a huge amount of reserve space
available in the AG here, so why not use some of the reserve space
to get out of this temporary deficit corner case? We can argue that
it's not really a deficit, either, because moving free blocks to the
free list still accounts them as unused and free, so could still
make up part of the unused reservation....
i.e. is the problem here simply that we don't allow AGFL blocks to
be considered part of the reserved free space?

I'm not sure if I got your point or not. I think it reserves another
full splits in the first allocation by doing:
need = xfs_alloc_min_freelist(mp, pag) * (1 + args->postallocs);
as I wrote above.

In the long term, I think the main point is that args->minleft doesn't
have the exact meaning. I don't know how many blocks should be counted
by args->minleft or other ways.

I don't know how to simply reuse per-AG reservation blocks for this,
and I think it could another corner case for this if it designs without
careful thinking. For the moment, I'd like to have a quick fix for
our all old kernels, and if it's possible, we'd like to upstream it
first.

You're changing the BMBT reservation code. If the first "post-extent
BMBT block allocation" does a full split of both the bno/cnt trees,
then this uses all the AGFL reservations made.
How many blocks does a BMBT split need to allocate?

args->minleft has an *exact* meaning - that the AG must have that
many blocks left available for potential btree record insertion
allocations after the initial extent is allocated. For inode fork
allocations, the BMBT blocks required is defined by
xfs_bmapi_minleft(). For inode chunk extent allocation and inobt
record insertion, it is defined by the pre-calculated
igeo->inobt_maxlevels variable.
IOWs, this "postalloc" concept is redundant - minleft already
provides the maximum number of single block allocations that need to
have space reserved in the AG for the initial extent allocation to
succeed. i.e. the allocation setup is already taking into account
blocks needed for extra allocations within the AG, but that's not
being handled correctly by the AG allocation code.
On review, it is quite possible that args->minleft is not being
handled by the BMBT and inobt block allocation code correctly.
Shouldn't btree block allocation drop args->minleft by 1 for
each block that is allocated?

I don't know either, which is *why I asked the question*. i.e. I'm
asking for you to investigate a potential alternative solution that
challenges a design assumption this code makes. i.e. AGBNO and AGCNT
btree blocks are considered free space because when we are at ENOSPC
they are empty.
However, with this ag reservation code, we can be at ENOSPC when
there are still tens of thousands of free extents, and hence the
AGBNO and AGCNT btree blocks are used space, not free space. The
AGFL accounting is based on AGFL blocks being considered free space,
which matches the AG btree blocks being considered free space, and
so maybe the root of the problem here is the assumption that AG
btree blocks and AGFL blocks are accounted as free space rather than
part of this new "reserved space"....

Slapping expedient bandaids into upstream kernels because some
vendor production kernel needs a quick fix is bad process and bad
policy.
"Upstream first" as a policy was originally intended for major
changes (e.g new features, design changes, on-disk format changes,
etc) to ensure that there is consensus on the changes and they've
been adequately reviewed before they get deployed to production
environments.
Over time, this has morphed into vendors defining "upstream first"
as "we can't ship any code unless it is upstream first". That's a
much different policy, and while the intention is good it is being
used more and more frequently as a big hammer to try to force
upstream to take poor code. i.e. it encourages vendor engineers to
"hack on a problem until it goes away, then get it merged upstream
because *urgent for production* and upstream first!!!!".
IOWs, "upstream first" is not intended as a mechanism to enable
band-aids to be applied so some random production system can avoid
an issue right now. "upstream first" as a policy is intended to get
the *right fix to production systems* as quickly as possible.
If anyone wants upstream to merge a band-aid that is easy to back
port, then it should be provided as the first patch in the series
that fixes the problem properly. The series that is merged needs to
effectively remove the technical debt the "easy to backport"
band-aid adds to the kernel. The end result in the upstream kernel
should always be "we fixed the problem to the best of our
abilities", not "we fixed the problem as quickly as possible"....
Cheers,
-Dave.

Emmm... I have to align my understanding of this first, I think one
example of what you meant is
1. allocate an extent for an inode with minleft = 1;
2. then do extents-to-btree allocation with one block, even minleft
was reserved as 1 in the previous allocation but such one-block
allocation from non-AGFL can cause full bno/cnt splits, which
could takes xfs_alloc_min_freelist() blocks from AGFL and could
take up all AGFL blocks?
If my understanding above is like what you said, I think the current
codebase may also have a chance to eat up all AGFL blocks in the first
allocation since more agfl blocks are only filled in
xfs_alloc_fix_freelist(), but later xfs_alloc_ag_vextent() could
cause full bno/cnt splits as well?
Please help correct me if my understanding about your ask is wrong.
>
> How many blocks does a BMBT split need to allocate?
IMO, a full bmbt split can allocate btree level blocks at maximum,
but if these block allocation cause bno/cnt btree splits, that
needs more than such blocks. So I think that's why AGFL is needed
for XFS. IOWs, that is to prepare enough blocks for bno/cnt splits
to avoid cyclic dependency.
But I'm not sure if the current AGFL reservation works properly
if multiple allocations must be succeeded in the same AG, see below..)

I don't think it's the case as I described in the patch commit message,
if we go over the words at the top, the main point is
In the first allocation, minleft = 1, the current allocator assumes
it can allocate an extent with 27 blocks (the remaining blocks are
18276 per-AG reservation, 6 for AGFL reservation, 1 for inode extents
-to-btree for the following allocation).
But here in order to finish this allocation with 27 blocks, it splits
cntbt so that it takes another unexpected block from AGFL, and
that wasn't accounted in minleft (or with any other fields) before.
I don't think it can be directly described by minleft because
such extra bno/cntbt reservation needs more knowledge of bno/cntbt
internals (such as current bno/cnt btree levels), so I don't think
it should belong to BMBT allocation code at least.
So here I introduced another variable to describe the total number
of post-allocations, I think it's just enough to resolve the inode
extents-to-btree bno/cntbt reservation issue.

At least, in order to convert from inode extents-to-btree, we need
another block for the following allocation, so minleft = 1 here.
if (ifp->if_format != XFS_DINODE_FMT_BTREE)
return 1;
So I guess what you meant is
return be16_to_cpu(ifp->if_broot->bb_level) + 1; ?
I don't know why it has another 1 here, yet even if we account an
extra block here, I think it doesn't have some critical result
since the worst case is that it just returns -ENOSPC in advance.
But in principle, most users use terabytes XFS, so I think such
one extra block doesn't matter too much. I will update this if
such 1 is meaningless, but it doesn't actually contribute to the
real shutdown issue.

I have strong feeling that the current per-AG reservation code (or
AGFL reservation as in xfs_alloc_min_freelist() ) doesn't work
properly for multiple allocations in the same AG in order to make
sure such multiple allocations all succeed.
Also, a wilder question is that I'm not sure why such multiple
allocations in oneshot _cannot_ be handled with a defer ops as
some new log intent, so that we don't need to care about minleft
messy anymore.

One request, could we discuss further about how to resolve this
issue properly on IRC? I really would like to take time to resolve
this issue formally and I can imagine it's not a easy fix.
Yet I think I need your/Darrick more inputs/tendency about this.
For now, I have to apply this patch to our production, otherwise,
it has very bad impacts to our cloud business by using XFS...
since user workloads could be shut down without any sign before.

Yes, the second allocation here might only require 1 block, which is
what args->minleft says. But the problem is that nothing is
reserving AGFL blocks for those nested extent allocations...
..... because the assumption is that AGFL blocks come from free
space and so when we are at ENOSPC bno/cnt btrees *do no require
splits* so will not consume extra space. Hence allocation at ENOSPC
doesn't need to take into account AGFL block usage because the AGFL
will not be consumed.
Similarly, if we have enough free space records to split a free
space btree block, we have enough free space to refill the AGFL
multiple times and we don't have to reserve space for them.
IOWs, the allocation code has, historically, never had to care about
AGFL refilling when the AG is near ENOSPC as nothing will consume
AGFL blocks when the AG is near empty.
This is the design assumption that AG reservations broke. This is
why I'm asking you to look into taking blocks that are supposedly
reserved for the AGFL, because as reserved space is used, the
bno/cnt btrees will shrink and return those blocks to free space and
hence they are still available for reserved allocations to use as
the real physical ENOSPC condition approaches.
The more I look at this, the more I think overall answer to this
problem is to allow AGFL refilling to ignore AG reserves rather than
causing ENOSPC....

The AGFL is there to ensure any *one* space allocation succeeds.

Right, it does not provide any guarantees across mutliple successive
allocations like an extent + BMBT split chain. That's what
args->minleft is supposed to provide.
However, it does provide the guarantee that when near ENOSPC,
bno/cnt splits and hence AGFL consumption will not occur, thereby
ensuring that if args->minleft is reserved correctly, operation
right up to ENOSPC will work correctly without AGFL reservations
because the AGFL will not be consumed.
Hence my comments above about the problem being the way AG
reservations moved ENOSPC from "AG physically empty" to "AG still
has thousands of free extents but remaining space unavailable to
user data allocation".

extents-to-btree is the degenerate case of a btree split. It's
moving the in-inode extent block to a single btree root block - it's
the same case as having a multi-level BMBT and splitting a single
leaf block during an xfs_btree_insert() call. Both require a second
discrete allocation to be made in the same transaction from the same
AG.
But if that xfs_btree_insert() call triggers a multi-level btree
split, we've now got more than 1 "post allocation" allocation being
done - there's one allocation for every level that needs to have a
block split. To handle this, we'd need to set up this args.postalloc
variable with the number of allocations a btree split might require.
What I'm trying to tell you is that args->minleft is already
configured with exactly this number of blocks/post-allocations that
the btree split might require, and hence allow the allocation code
to select an AG with the right amount of space needed before it
starts.

Yes, as I said above, that's the degenerate case where we only need
to allocate a root block and set the btree level to 1.

It's a btree. What does a full height btree split do?
It adds a block to each existing level, and splits the root block
into two. Which means we need to increase the tree height by 1 and
allocate a new root block. IOWs, the number of allocations/blocks
needed by a full split is (current height + 1).

I think you misunderstood what I was asking. Let's unroll the
extent allocation/BMBT record insert loop:
extent allocation
args.minleft = bb_level + 1
xfs_alloc_vextent(args)
bmbt record insert
xfs_btree_insert()
leaf split
xfs_bmbt_alloc_block()
args.minleft = ???
xfs_alloc_vextent(args)
level 1 node split
xfs_bmbt_alloc_block()
args.minleft = ???
xfs_alloc_vextent(args)
level 2 node split
xfs_bmbt_alloc_block()
args.minleft = ???
xfs_alloc_vextent(args)
....
root split
xfs_bmbt_alloc_block()
args.minleft = ???
xfs_alloc_vextent(args)
A BMBT split results in a chain of individual allocations. What
should args.minleft be set to on each of these allocations, and
what context do we have to ensure it is set correctly?
So the question I was asking was whether what we are doing with
args->minleft for each allocation in the chain is correct, and
whether they need modification if we have to take into account the
AGFL block refilling that may need to occur after each BMBT block
allocation?
Indeed, if we get the initial extent allocation reservation correct,
does minleft even matter for the rest of the allocations in the
chain?
Looking at xfs_bmbt_alloc_block(), it sets args.minleft = 0 if there
was a previous allocation in the transaction (i.e. args.fsbno !=
NULLFSBLOCK). It assumes that the original extent reservation set
args.minleft appropriately to reserve enough space for all
subsequent calls to xfs_bmbt_alloc_block() in this transaction to
succeed.
Hence, given the way it is implemented right now, all we need to do
is ensure that the initial allocation has all the space reservation
the entire operation may need and the rest is good, yes?
xfs_bmap_extents_to_btree() also sets args->minleft = 0, so as long
as the first allocation in the transaction has reserved enough
blocks in args->minleft it doesn't need any special help, either.
So, yes, you are right that avoiding ENOSPC when running multiple
allocations in a single transaction is all based on the initial
allocation ensuring there is enough space in the AG for all
subsequent allocations to succeed. But there's a lot more to it than
that....

We do use intents and deferred ops for BMBT freeing and reflink
based insertion, but those only log changes to individual records in
the btree. They do not record internal btree shape changes at all.
Yes, we could convert normal extent allocation to use these intents
as well, but that doesn't solve the problem of chained allocations
within a single AG.
IOWs, the chain of allocations for a BMBT split I mention above
still exists for record level intents. To handle the btree split
case as a chain of intents involves a whole new level of complexity
and overhead in the btree code, and likely introduces more problems
at ENOSPC than it solves...
Cheers,
Dave.

Thanks for your detailed reply.
Sorry for late reply. I pinged you on IRC last Friday but seems you are
busy, so I try to reply here as well.

I noticed another thing. I think the reason why the first allocation
in this case caused a cntbt split is that Zorro's workload set
sunit/swidth. Therefore, due to align requirement, I assume it
called xfs_alloc_fix_len() to fix up agbno and len.
Actually I found our workload has the similar sunit/swidth setup and
I am thinking about this these days. One thing is that why we need
freespace btree splits when consuming free blocks.
Another thing is that considering we're near ENOSPC, and bno/cnt
btrees has only a few records. If we allocates without alignment,
I also think bno/cnt btrees do no require splits so it will not
consume extra space since the overall extents only decrease.
Yet how about allocating with alignment? It seems that it can add
another free extent in order to fulfill the alignment. I'm not sure
if it can cause some corner cases here.

Yeah, intuitively I also imagine like what you said. However, does it
have strictly monotonicity, especially with stripe alignment setup?

Could you give more details how to fit this case? Also we have a
short talk last Wednesday (sorry that I had an urgent thing at that
time). You mentioned "the simple solution is something like
min(ag reservation blocks, needed AGFL blocks) instead of accounting
them separately", could you give an example for this case as well?
Nevertheless, I wonder if `need` now can be fixed up as
need = xfs_alloc_min_freelist(mp, pag) * (1 + args->minleft);

Partially because of that, the main reason I think may be due to

My question was that if we convert some allocations into dfops, does
inode extents-to-btree needs to be strictly allocated in this AG
anymore? ... Does that tend to be a long-term plan?
Sorry I'm not good at replying a long email, hopefully reflect what I'm

stripe alignment does not affect AGFL behaviour, not free space
btree allocation requirements. stripe alignment only affects the
initial user data allocations from xfs_bmap_btalloc() where the
stripe alignment variables (e.g. min align, align slop, etc). None
of these parameters are set for AGFL or btree block allocations, so
they ignore all alignment constraints.

Alignment never requires an extra allocation - it reserves extra
space to select a larger freespace that an aligned extent can be
carved out of. If an aligned extent cannot be found, we fall back to
unaligned allocation....

Go read the head comment in xfs_ag_resv.c. Specifically, this bit:
* Reserved blocks can be managed by passing one of the enum xfs_ag_resv_type
* values via struct xfs_alloc_arg or directly to the xfs_free_extent
* function. It might seem a little funny to maintain a reservoir of blocks
* to feed another reservoir, but the AGFL only holds enough blocks to get
* through the next transaction. The per-AG reservation is to ensure (we
* hope) that each AG never runs out of blocks. Each data structure wanting
* to use the reservation system should update ask/used in xfs_ag_resv_init.
This was originally written with RMAPBT updates in mind (rmap btree
blocks come from the AGFL, just like the bno/cnt btrees). SInce this
was written, AGFL blocks have been carved out of this reservation by
XFS_AG_RESV_AGFL, and so this reservation space no longer reserves
or accounts for refilling the AGFL for non-RMAPBT operations.
My point is, however, that the reservation space was intended for
ensuring the AGFL could be refilled without triggering ENOSPC in
certain circumstances. And here we are with a situation where
refilling the AGFL triggers ENOSPC because of the reservation
space.
The "available" calculation in xfs_alloc_space_available() does:
available = (int)(pag->pagf_freeblks + agflcount -
reservation - min_free - args->minleft);
Which is effectively:
available = (free space) -
(reserved space) -
(minimum AG requires to be left free) -
(minimum allocation requires to left free)
But what we have to consider is that three of these parameters have
a component of "AGFL blocks" in them:
free space = indexed free space + current AGFL blocks
reserved space = space reserved for future AGFL block allocation
minimum AG free = AGFL blocks needed for this allocation
Looked at a different way (as a timeline):
free space = Previously allocated AGFL blocks
reserved space = future allocation AGFL block pool
minimum free = present allocation AGFL needs
So the problem you are seeing is that on the second allocation of a
chain, the AGFL blocks previously allocated by the initial
allocation in the chain are not sufficient for present AGFL needs
and we do not allow the present allocation to use space from the
future AGFL block pool to fill the AGFL....
Also, we need to keep in mind that the initial allocation uses
args->resv = XFS_AG_RESV_NONE, so the reservation space returned for
the initial allocation is the full metadata (finobt) + reserved
(RMAPBT) reservation that is being made.
The second allocation in the chain (where minleft is zero) really
needs to have a reserve pool for AGFL filling. But we don't have a
reserve pool for general AGFL allocations anymore, and this looks
like we need it. i.e. instead of XFS_AG_RESV_AGFL just being used to
avoid accounting AGFL block usage, perhaps it should actually manage
a reserve pool for ensuring the AGFL can be refilled near ENOSPC
(due to outstanding RMAP/FINOBT reservations) in a single
transaction allocation chain....
i.e. so long as the pool has more blocks in it than the current
allocation requires to refill the AGFL, the allocation can
proceed...

It's not in any of my plans.
The problem with moving to "any AG" allocation is that BMBT block
allocation is now subject to AGF locking rules and availability.
Say, for example, we have 4 AGs and we just allocated the initial
extent in AG 3 (the last AG) - we only have one safe choice of AG we
can allocate from due to AGF lock ordering. If we don't ensure that
the BMBT blocks can be allocated from the same AG as the initial
allocation, we lose the ability to guarantee that the BMBT blocks
(and INOBT blocks) will be allocated without an ENOSPC condition
occurring.
If we get ENOSPC part way through a BMBT or INOBT update regardless
of whether we are rolling the transaction via deferops or just a
single transaction allocation change, we have to cancel the
currently running transaction. The transaction will be dirty at this
point, and cancelling a dirty transaciton shuts down the filesystem.
IOWs, failing to guarantee that the entire allocation chain will
succeed results in turning a simple ENOSPC error being reported to
userspace into a full filesystem shutdown....
Cheers,
Dave.

Thanks for your report!
At a glance, I have no idea why this commit can have performance
impacts. Is the result stable?

please be noted we noticed Gao Xiang and Dave Chinner have already had lots of
discussion around this patch, which seems there is maybe new version later.
we just sent out this report FYI the possible performance impact of this patch.
Greeting,
FYI, we noticed a -15.1% regression of fxmark.ssd_xfs_MWCM_72_directio.works/sec due to commit:

To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.

This MWCM workload uses a shared directory. Every worker thread (72
of them) iterates creating a new file, writes 4kB of data to it and
then closes it. There is no synchronisation between worker threads.
The worker threads will lockstep on the directory lock for file
creation, they will all attempt to allocate data in the same AG as
the file is created. Hence writeback will race with file creation
for AG locks, too. Once the first AG is full, they will all attempt
to allocate in the next AG (file creation and writeback).
IOWs, this workload will race to fill AGs, will exercise the "AG
full so skip to next AG" allocator fallbacks, etc.
Changing where/how AGs are considered full will impact how the AG
selection is made. I'm betting that there's a mismatch between the
code that selects the initial AG for allocation (from
xfs_bmap_btalloc() via the nullfb case) and the code that selects
the actual AG for allocation (xfs_alloc_vextent() w/ NEAR_BNO
policy) as a result of this change. This then results in
xfs_alloc_vextent() trying to initially allocate from an AG that
xfs_alloc_fix_freelist() considers to be full, so it skips the
initial selected AG and starts searching for an AG it can allocate
into.
Combine that with AGF lock contention from 70+ tasks all trying to
allocate in the same location...
Cheers,
Dave.

I meant allocation strategy change may cause this, but I didn't think it
could cause such impact. I will reconfirm on my own side as well.

Glad to know about that. I didn't look into the MWCM workload before.

I can imagine, but I didn't think out several block reservation could
cause such huge impacts.

Yeah, anyway, I will reconfirm on our side about this workload
as well.

Hi Dave,
Sorry for some delay again (I was applying some workaround to our
production to mitigate this and some other stuffs around there.)

As we talked on IRC, I skip this part now. In brief, I think stripe

I agree with your word here.

Ok, let me think out a way to use ag_resv framework to resolve this
issue now.
