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.

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
