[GIT PULL] f2fs fixes for 3.16

[Jaegeuk Kim]

Hi Linus,

This is a pull request on f2fs bug fixes for v3.16, which 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.

Thank you very much.
