Thanks a lot for the patch!
Offering help is okay, but the SR thing had a really bad taste.
Iff mainline is not vulnerable, no problem but please communicate such
a fact clearly.
Also if your patch is not yet through your in-house QA, you can still
send an "hey-i-have-an-idea..."-patch.

Is the git repo listed in MAINTAINERS and the ocfs2 website still valid?
It looks kinda outdated...
git://git.kernel.org/pub/scm/linux/kernel/git/jlbec/ocfs2.git

OCFS2 development seems to be very opaque currently.
