[PATCH] Btrfs-progs: skip extent rebuild test if no testdev

[PATCH] Btrfs-progs: skip extent rebuild test if no testdev

[Josef Bacik]

It is highly obnoxious to have to go put in a testdev when all you really want
is to run the quick image tests.  Make this part optional so if we don't have a
testdev specified we just don't run that particular test.  Thanks,
