Please submit the patch immediately.
Why does one need a f§&"!#$ SR from Oracle to have this fixed?
OCFS2 is mainline...

So, where can I find this patch?
Can you please share it with us insignificant and rubbishy community folks?

https://oss.oracle.com/projects/ocfs2/source.html points to

This tree seems horrible outdated...

Looks like Al took some ocfs2 patches directly to his vfs GIT tree(s)
and sent to mainline.

Here is the patch against mainline which I haven't yet submitted because 
I have not finished testing on mainline kernel yet. I am running into 
another unrelated crashes during testing. I am forwarding the patch to 
you assuming you are looking for this fix.

https://oss.oracle.com/~seeda/patches/dlm-race/

The other person who emailed about the problem was running older ocfs2 
version(1.4-10). Which is where I originally debugged, patched and 
tested the fix. So I offered to help him.

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It looks kinda outdated...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.
