Subject: xfstests: renumber existing btrfs tests to start with 1
X-Git-Tag: v2022.05.01~3396
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=aab6d4e47d51b5cf4e5fc4a15a5dee80fb72aab4;p=xfstests-dev.git

xfstests: renumber existing btrfs tests to start with 1

Current numbering is inheried from the single testsuite series. There
are only 6 btrfs-specific tests and it makes more sense to start adding
new ones at a more natural place than 300-something. There's no overlap
with the old and new numbers and I hope there' will be no confusion when
referencing them.
