Merge tag 'f2fs-fixes-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs bugfixes from Jaegeuk Kim:
"This includes a couple of bug fixes found by xfstests. In addition,
one critical bug was reported by Brian Chadwick, which is falling into
the infinite loop in balance_dirty_pages. And it turned out due to
the IO merging policy in f2fs, which was newly merged in 3.16.
- fix normal and recovery path for fallocated regions
- fix error case mishandling
- recover renamed fsync inodes correctly
- fix to get out of infinite loops in balance_dirty_pages
- fix kernel NULL pointer error"
