Description of problem:
Got this (see attachment to this bz) after mounting the gfs2 volume with acl option. Not really sure if it is new or related to my previous deadlock problems, but thought I better submit it. Maybe your latest patches are not in this kernel and this is taken care of in your tree. I was doing a couple finds. You will all see a sysreq dump included in case it helps. Runnig devel version, kernel kernel-devel-2.6.18-1.2849.fc6 and the latest updates to cman, clvm, openais, etc.
FWIW, the find process is hung chewing through 100% CPU, I assume spinning on a lock...
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Sorta reproducible (intermittant)
1. Mount gfs2 volume with acl?
2. use find to find a file
Find a file (or not) with kernel errors
Find a file (or not) without kernel errors///

Kernel errors for gfs2 with ACL mount option
Kernel errors and sysreq dump of problem...
This is caused by some incorrect logic when checking the acl which hasn't
correctly worked out whether the inode is already locked or not and has tried to
lock it again. I'll try to come up with a patch shortly.
I've just pushed a patch to the -nmw git tree to fix this problem.
This is the URL of the fix:
I would have posted it yesterday, but it seems that kernel.org is very slow to
update these days. You can get a plain version from the "plain" link at the top
of the web page.
Fixed in FC6 kernel 2.6.19-1.2895
