Hi Linus,
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.
Thank you very much.

f2fs: support volatile operations for transient data (2014-10-07 11:54:41 -0700)
----------------------------------------------------------------
f2fs updates for v3.18
This series includes patches to:
o retain some recovery information for fsck.f2fs
o enhance checkpoint speed
o enhance flush command management
o bug fix for lseek
o tune in-place-update policies
o enhance roll-forward speed
o revisit all the roll-forward and fsync rules
o support large sector size
o support FITRIM
o support atomic and volatile writes
And several clean-ups and bug fixes are included.
