Hi,
this time the majority of changes are cleanups, though there's still a
number of changes of user interest. Please pull, thanks.
User visible changes:
- better read time and write checks to catch errors early and before
writing data to disk (to catch potential memory corruption on data that
get checksummed)
- qgroups + metadata relocation: last speed up patch int the series to
address the slowness, there should be no overhead comparing balance with
and without qgroups
- FIEMAP ioctl does not start a transaction unnecessarily, this can result
in a speed up and less blocking due to IO
- LOGICAL_INO (v1, v2) does not start transaction unnecessarily, this can
speed up the mentioned ioctl and scrub as well
- fsync on files with many (but not too many) hardlinks is faster, finer
decision if the links should be fsynced individually or completely
- send tries harder to find ranges to clone
- trim/discard will skip unallocated chunks that haven't been touched
since the last mount
Fixes:
- send flushes delayed allocation before start, otherwise it could miss
some changes in case of a very recent rw->ro switch of a subvolume
- fix fallocate with qgroups that could lead to space accounting underflow,
reported as a warning
- trim/discard ioctl honours the requested range
- starting send and dedupe on a subvolume at the same time will let only
one of them succeed, this is to prevent changes that send could miss due
to dedupe; both operations are restartable
Core changes:
- more tree-checker validations, errors reported by fuzzing tools
- device item
- inode item
- block group profiles
- tracepoints for extent buffer locking
- async cow preallocates memory to avoid errors happening too deep in the
call chain
- metadata reservations for delalloc reworked to better adapt in
many-writers/low-space scenarios
- improved space flushing logic for intense DIO vs buffered workloads
- lots of cleanups
- removed unused struct members
- redundant argument removal
- properties and xattrs
- extent buffer locking
- selftests
- use common file type conversions
- many-argument functions reduction
