Hi Linus,

Here is the pull request on f2fs updates for v3.12.
This patch-set includes several enhancements such as inline-xattrs, sysfs,
proc entry, and performance improvement at worst case scenarios.
It also includes some bug fixes.
Thank you very much.

  f2fs: optimize gc for better performance (2013-09-05 13:50:32 +0900)

----------------------------------------------------------------
f2fs updates for v3.12

This patch-set includes the following major enhancement patches.

o add proc entry to show the current segment usage information
o improve the GC/SSR performance

The other bug fixes are as follows.
o avoid the overflow on status calculation
o fix some error handling routines
o fix inconsistent xattr states after power-off-recovery
o fix incorrect xattr node offset definition
o fix deadlock condition in fsync
o fix the fdatasync routine for power-off-recovery
