Hi Chris,
This is the small cleanup and fixes for 4.2. Compared to the previous
pull, this one is quite small, only 2 cleanup and one small quota fix.

The search key advancing condition used in copy_to_sk() is loose. It can
advance the key even if it reaches sk-max_*: e.g. when the max key = (512,

offset by 1, continues hopeless search from (512, 1025, 11). This issue

To Chris:
Would you consider merging these patchset for late 4.2 merge window?
If it's OK to merge it into 4.2 late rc, we'll start our test and send
pull request after our test, eta this Friday or next Monday.
I know normally we should submit it early especially when such fix is
not small.
Make sure that running reflink ops while other IO is ongoing doesn't
break the filesystem.

Hi all,
This is a RFC-quality pass at making xfstests perform more rigorous
testing of the btrfs/xfs file clone, reflink, and dedupe ioctls.
There are now tests of the basic functionality of the three ioctls;
tests to ensure that the filesystem exhibits the expected copy on
write semantics; tests
Introduce tests for XFS and ext4 which format a filesystem, populate
it, then uses blocktrash and e2fuzz to corrupt the metadata. The FS
is remounted, modified, and unmounted. Following that, xfs_repair or
e2fsck are run until it no longer finds errors to correct, after which
the FS is mounted
Check that growfs and xfs_fsr still work properly on reflinked fses.
