Subject: [PATCH 3.16 048/133] f2fs: check hot_data for roll-forward recovery

3.16.51-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Jaegeuk Kim <jaegeuk@...nel.org>

commit 125c9fb1ccb53eb2ea9380df40f3c743f3fb2fed upstream.

We need to check HOT_DATA to truncate any previous data block when doing
roll-forward recovery.
