Merge tag 'f2fs-for-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "This patch-set introduces a couple of new features such as large
  sector size, FITRIM, and atomic/volatile writes.

  Several patches enhance power-off recovery and checkpoint routines.

  The fsck.f2fs starts to support fixing corrupted partitions with
  recovery hints provided by this patch-set.

  Summary:
   - retain some recovery information for fsck.f2fs
   - enhance checkpoint speed
   - enhance flush command management
   - bug fix for lseek
   - tune in-place-update policies
   - enhance roll-forward speed
   - revisit all the roll-forward and fsync rules
   - support larget sector size
   - support FITRIM
   - support atomic and volatile writes

  And several clean-ups and bug fixes are included"

ipu_policy This parameter controls the policy of in-place
updates in f2fs. There are five policies:
0: F2FS_IPU_FORCE, 1: F2FS_IPU_SSR,
2: F2FS_IPU_UTIL, 3: F2FS_IPU_SSR_UTIL,
4: F2FS_IPU_DISABLE.

0x04: F2FS_IPU_UTIL, 0x08: F2FS_IPU_SSR_UTIL,
0x10: F2FS_IPU_FSYNC.
min_ipu_util This parameter controls the threshold to trigger
in-place-updates. The number indicates percentage
of the filesystem utilization, and used by
F2FS_IPU_UTIL and F2FS_IPU_SSR_UTIL policies.
min_fsync_blocks This parameter controls the threshold to trigger
in-place-updates when F2FS_IPU_FSYNC mode is set.
The number indicates the number of dirty pages
when fsync needs to flush on its call path. If
the number is less than this value, it triggers
in-place-updates.
max_victim_search This parameter controls the number of trials to
find a victim segment when conducting SSR and
cleaning operations. The default value is 4096
