[GIT PULL] f2fs updates for v3.18

From: Jaegeuk Kim
Date: Wed Oct 08 2014 - 01:57:13 EST

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:
