[Ocfs2-devel] [PATCH 0/3] ocfs2: move hb_ctl into stack glue

[Joel Becker]

We have determined that ocfs2 can only leave a cluster group safely in
put_super(7).  The presence of bind mounts, rbind mounts, and shared
subtrees make tracking mountpoints impossible in userspace.

To solve this, we move the ocfs2_hb_ctl call out of o2cb and into the
generic stack glue code.  ocfs2_hb_ctl will always be called for all
cluster stacks.  This should be compatible with old and new tools - o2cb
behavior doesn't change.

The code is also available on the 'hbctl-path' branch of my git
repository.
