Subject: btrfs: tests, move initialization into tests/
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8632daae40c1a5b8fcc1d66d788c143353fd70b7;p=linux-beck.git

btrfs: tests, move initialization into tests/

We have all these stubs that only exist because they're called from
btrfs_run_sanity_tests, which is a static inside super.c.  Let's just
move it all into tests/btrfs-tests.c and only have one stub.
