From: Eric Sandeen Date: Fri, 10 Mar 2017 03:57:11 +0000 (+0800) Subject: generic: test orphan inode recovery on RO mount X-Git-Tag: v2022.05.01~2128 X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=265c1037eeaf2fa9e4c0cede132c22b3cadf9fb8;p=xfstests-dev.git generic: test orphan inode recovery on RO mount There's a bug in xfs where the orphan inode list is not processed on a readonly mount, and is still not processed even if it gets mounted rw. This test exercises that, and makes sure that the unlinked list is empty after a transition to rw and an unmount. While we're at it, sanity check the same thing for pure ro and rw unmounts. Now that shutdown is generic, we can test other filesystems as well, so this is in the generic group.
