Merge tag 'for-f2fs-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, there is no special interesting feature, but we've
investigated a couple of tuning points with respect to the I/O flow.
Several major bug fixes and a bunch of clean-ups also have been made.
This patch-set includes the following major enhancement patches:
- enhance wait_on_page_writeback
- support SEEK_DATA and SEEK_HOLE
- enhance readahead flows
- enhance IO flushes
- support fiemap
- add some tracepoints
The other bug fixes are as follows:
- fix to support a large volume > 2TB correctly
- recovery bug fix wrt fallocated space
- fix recursive lock on xattr operations
- fix some cases on the remount flow
And, there are a bunch of cleanups"
