  ext4: set lazytime on remount if MS_LAZYTIME is set by mount (2015-06-23 11:03:54 -0400)

----------------------------------------------------------------
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.
