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" * tag 'for-f2fs-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (52 commits) f2fs: support f2fs_fiemap f2fs: avoid not to call remove_dirty_inode f2fs: recover fallocated space f2fs: fix to recover data written by dio f2fs: large volume support f2fs: avoid crash when trace f2fs_submit_page_mbio event in ra_sum_pages f2fs: avoid overflow when large directory feathure is enabled f2fs: fix recursive lock by f2fs_setxattr MAINTAINERS: add a co-maintainer from samsung for F2FS MAINTAINERS: change the email address for f2fs f2fs: use inode_init_owner() to simplify codes f2fs: avoid to use slab memory in f2fs_issue_flush for efficiency f2fs: add a tracepoint for f2fs_read_data_page f2fs: add a tracepoint for f2fs_write_{meta,node,data}_pages f2fs: add a tracepoint for f2fs_write_{meta,node,data}_page f2fs: add a tracepoint for f2fs_write_end f2fs: add a tracepoint for f2fs_write_begin f2fs: fix checkpatch warning f2fs: deactivate inode page if the inode is evicted f2fs: decrease the lock granularity during write_begin ...
