OCFS2 mainline state?

[Richard Weinberger]

Hi!

Today I encountered the following problem on v3.8:
[   28.940032] general protection fault: 0000 [#1] PREEMPT SMP
...
[   28.984953] Call Trace:

To my utter astonishment I found out that the issue is known since August 2012.
And there is also a trivial fix for it.[0]
The said fix found it's way into Oracle Unbreakable Linux very quickly,
but not into mainline.[1]

Now I'm wondering how much Oracle really cares about OCFS2 in mainline?
Maybe there are some more unfixed vulnerabilities?

Not amused,
