[Ocfs2-users] OCFS2 + DRBD 0.81 Casch

[Sunil Mushran]

The patch fix for this missed the 2.6.20 window.

The following link has all the relevant patches atop 2.6.20.
http://git.kernel.org/?p=linux/kernel/git/mfasheh/ocfs2.git;a=log;h=2.6.20_fixes

Apply all in order starting from one after the official 2.6.20.

Incidentally the fix you require is the first on the list.
