  ext4: verify extent header depth (2016-07-15 00:22:07 -0400)

----------------------------------------------------------------
The major change this cycle is deleting ext4's copy of the file system
encryption code and switching things over to using the copies in
fs/crypto.  I've updated the MAINTAINERS file to add an entry for
fs/crypto listing Jaeguk Kim and myself as the maintainers.

There are also a number of bug fixes, most notably for some problems
found by American Fuzzy Lop (AFL) courtesy of Vegard Nossum.  Also
fixed is a writeback deadlock detected by generic/130, and some
potential races in the metadata checksum code.
