There are a few hard to reproduce bugs in xfs_repair where it can deadlock trying to lock a buffer that it already owns. These stalls cause fstests never to finish, which is annoying! To fix this, set up the xfs_repair run to abort after 10 minutes, which will affect the golden output and capture a core file. This doesn't fix xfs_repair, obviously. Signed-off-by: Darrick J.
