Re: [PATCH 2/2] xfstests: add a rename fsync test

[Christoph Hellwig]

Both patches look good to me, but I haven't actually run the new
testcase yet..

[PATCH 1/2] xfstests: add generic/321 to test fsync() on directories V2

[Josef Bacik]

Btrfs had some issues with fsync()'ing directories and fsync()'ing after
renames.  These three new tests cover the 3 different issues we were seeing.
This breaks out the dmflakey stuff into a common helper to be shared between
generic/311 and generic/321. Thanks,
