Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 updates from Ted Ts'o: "A very large number of cleanups and bug fixes --- in particular for the ext4 encryption patches, which is a new feature added in the last merge window. Also fix a number of long-standing xfstest failures. (Quota writes failing due to ENOSPC, a race between truncate and writepage in data=journalled mode that was causing generic/068 to fail, and other corner cases.) Also add support for FALLOC_FL_INSERT_RANGE, and improve jbd2 performance eliminating locking when a buffer is modified more than once during a transaction (which is very common for allocation bitmaps, for example), in which case the state of the journalled buffer head doesn't need to change" [ I renamed "ext4_follow_link()" to "ext4_encrypted_follow_link()" in the merge resolution, to make it clear that that function is _only_ used for encrypted symlinks. The function doesn't actually work for non-encrypted symlinks at all, and they use the generic helpers - Linus ] * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (52 commits) ext4: set lazytime on remount if MS_LAZYTIME is set by mount ext4: only call ext4_truncate when size <= isize ext4: make online defrag error reporting consistent ext4: minor cleanup of ext4_da_reserve_space() ext4: don't retry file block mapping on bigalloc fs with non-extent file ext4: prevent ext4_quota_write() from failing due to ENOSPC ext4: call sync_blockdev() before invalidate_bdev() in put_super() jbd2: speedup jbd2_journal_dirty_metadata() jbd2: get rid of open coded allocation retry loop ext4: improve warning directory handling messages jbd2: fix ocfs2 corrupt when updating journal superblock fails ext4: mballoc: avoid 20-argument function call ext4: wait for existing dio workers in ext4_alloc_file_blocks() ext4: recalculate journal credits as inode depth changes jbd2: use GFP_NOFS in jbd2_cleanup_journal_tail() ext4: use swap() in mext_page_double_lock() ext4: use swap() in memswap() ext4: fix race between truncate and __ext4_journalled_writepage() ext4 crypto: fail the mount if blocksize != pagesize ext4: Add support FALLOC_FL_INSERT_RANGE for fallocate ...
