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"
