[PATCH] xfstests: add test for btrfs send issuing premature rmdir operations

[Filipe David Borba Manana]

Regression test for btrfs incremental send issue where a rmdir instruction
is sent against an orphan directory inode which is not empty yet, causing
btrfs receive to fail when it attempts to remove the directory.

This issue is fixed by the following linux kernel btrfs patch:

   Btrfs: fix send attempting to rmdir non-empty directories

This is duplicated across several tests now. Perhaps this should be
factored now into a _requires_fssum helper (separate patch is
fine)?

you should be able to use _check_scratch_fs() here. I note that the
btrfs path does not unmount the scratch device, so you should update
it to do so (like _check_xfs_filesytem does) and then
_check_scratch_fs() will just Do The Right Thing.

Hasn't run_check already redirected everything to $seqres.full?

_check_scratch_fs() here too.

[PATCH v2] xfstests: add test for btrfs send issuing premature rmdir operations

[Filipe David Borba Manana]

Regression test for btrfs incremental send issue where a rmdir instruction
is sent against an orphan directory inode which is not empty yet, causing
btrfs receive to fail when it attempts to remove the directory.

This issue is fixed by the following linux kernel btrfs patch:

   Btrfs: fix send attempting to rmdir non-empty directories

Signed-off-by: Filipe David Borba Manana <fdmanana@gmail.com>
---

V2: Some cleanup as suggested by Dave Chinner. Use _check_scratch_fs() and
    removed redundant stderr redirection when calling fssum via run_check.

All done in V2 (same for the other test).
For the require_fssum() function, I made a patch on top of these 2 so
that it updates all existing btrfs tests that need fssum ("[PATCH]
xfstests: add function _require_fssum()").

Thanks for the good suggestions Dave.
