Subject: [git pull] Fix recent Ocfs2 breakage
Date: Mon, 28 Jan 2008 19:33:07 -0800	[thread overview]
Message-ID: <> (raw)

Greg's commit c60b71787982cefcf9fa09aa281fa8c4c685d557 inadvertantly broke
Ocfs2 userspace ABI, so I have a rather high priority single line patch from
Joel to fix things up for you to pull. A copy of the patch is attached to
the bottom of this e-mail. Embarassingly enough, I missed this while acking
the patch late last week :(

Please pull from 'upstream-linus' branch of
git:// upstream-linus

ocfs2: Fix userspace ABI breakage in sysfs

The userspace ABI of ocfs2's internal cluster stack (o2cb) was broken by
commit c60b71787982cefcf9fa09aa281fa8c4c685d557 "kset: convert ocfs2 to
use kset_create".  Specifically, the '/sys/o2cb' kset was moved to
'/sys/fs/o2cb'.  This breaks all ocfs2 tools and renders the
filesystem unmountable.

This fix moves '/sys/o2cb' back where it belongs.
