From: Filipe Manana <fdmanana@xxxxxxxx>
Hi Chris,
Please consider the following changes for the merge window for 4.7.
There's an implementation for the rename exchange and rename whiteout
operations, from Dan Fuhry, which was originally in David's integration
branches and linux-next but then we agreed to move it into my branches
since I made a few fixes on top of it. Other than that, there's just the
usual set of bug fixes, in particular races between direct IO writes and
fsync and between direct IO writes and balance, which lead to data loss
and metadata corruption issues.
These were recently rebased just to add Reviewed-by tags from Josef and
Liu Bo, but otherwise unchanged and have been in testing for quite some
time here.
Thanks.
