f2fs: cover free_nid management with spin_lock (2013-05-08 13:22:05 +0900)
----------------------------------------------------------------
f2fs updates for v3.10
This patch-set includes the following major enhancement patches.
o introduce a new gloabl lock scheme
o add tracepoints on several major functions
o fix the overall cleaning process focused on victim selection
o apply the block plugging to merge IOs as much as possible
o enhance management of free nids and its list
o enhance the readahead mode for node pages
o address several cretical deadlock conditions
o reduce lock_page calls
The other minor bug fixes and enhancements are as follows.
o calculation mistakes: overflow
o bio types: READ, READA, and READ_SYNC
o fix the recovery flow, data races, and null pointer errors

Hi,
Thank you for the report.
I'm not able to reproduce this at all.
In my runs, there was no regression.
Can you do that?
Thanks,

Hi Linus,
Here is the pull request on f2fs updates for v3.11.
Most of patches in this patch-set have been proposed to fix the
roll-forward mechanism significantly.
One of major fixes is related to little and big endian conversion, and
its errorneous symptom on powerpc was initially reported by Oded Gabbay.
Another one is that it has been revealed the pgbench regression reported
by phoronix was caused by one of fsync bug fixes in 3.10-rc1. In order
to restore the performance, one enhancement patch was introduced in this
patch-set, which is f2fs: recover wrong pino after checkpoint during
fsync.
One of new features is *xattr security labels* which is essential to the
SEandroid system.
Please consider pulling the following tag.
Thank you,

f2fs: fix to recover i_size from roll-forward (2013-07-02 08:48:16
+0900)
----------------------------------------------------------------
This patch-set includes the following major enhancement patches.
o remount_fs callback function
o restore parent inode number to enhance the fsync performance
o xattr security labels
o reduce the number of redundant lock/unlock data pages
o avoid frequent write_inode calls
The other minor bug fixes are as follows.
o endian conversion bugs
o various bugs in the roll-forward recovery routine
