[PATCH v2 0/3] xfstests: fix tests for rmap/reflink

[Darrick J. Wong]

Hi all,

Here are some cleanups[1] for the rmap/reflink tests to reflect recent
API changes (the readdition of the unshare fallocate flag and the
removal of the reflink inode flag), a last-minute disk format change
for the XFS reflink implementation, and some cleanups that were left
out of the previous patch submission.

[PATCH 1/3] xfs: set the refcount btree cowflag when setting up cow

[Darrick J. Wong]

When we're setting up a fake cow extent in the refcountbt to test
cleanup of fake cow extents, set the cowflag in the record field
to reflect our new disk format of storing the staging extents in
the right side of the tree.

[PATCH 2/3] misc: fix fallocate commands that need the unshare switch

[Darrick J. Wong]

We re-added the UNSHARE flag to fallocate, so go make sure that all
the unshare tests actually check that the installed copy of xfs_io
supports the 'funshare' command and that the underlying filesystem
understands the flag, and change the tests themselves to use
funshare.

[PATCH 3/3] misc: fix more xfs_db open-coding instances

[Darrick J. Wong]

Convert some more cases of 'xfs_db $SCRATCH_DEV' to _scratch_xfs_db
that were left out of the initial cleanup patch.

[PATCH 1/3] xfs: set the refcount btree cowflag when setting up cow

[Darrick J. Wong]

When we're setting up a fake cow extent in the refcountbt to test
cleanup of fake cow extents, set the cowflag in the record field
to reflect our new disk format of storing the staging extents in
the right side of the tree.
