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.

The following changes since commit 70c8038dd698b44daf7c8fc7e2eca142bec694c4:

  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

And several clean-ups and bug fixes are included.
