Ted Ts'o has sent in the big batch of EXT4 file-system updates for the Linux 4.2 kernel merge window.

Following EXT4 adding encryption support to Linux 4.1, there's many fixes/clean-ups in Linux 4.2 for the new encryption code. Beyond sprucing up the EXT4 encryption code there's many other cleanups and fixes, including some xfstest failures that have been taken care of.

A new feature for EXT4 in Linux 4.2 is support for the FALLOC_FL_INSERT_RANGE flag. FALLOC_FL_INSERT_RANGE inserts zeroed-out space in between the file with the range specified, coming in as the opposite of the collapse range flag.

A full listing of the EXT4 changes for Linux 4.2 can be found via the pull request.
