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"
