Thanks a lot for your quick response and comment.

We hope to make corrections better and incorporate them into mainline by 
with the review. 

The primary test which we've been using for those reported cases is to mount
and umount from multiple nodes at the same time.
mkfs.ocfs2 --cluster-stack=pcmk --cluster-name=debian -N <N> /dev/blkdevice

while true; do
  dsh -c -m node1,node2,node3...node<N> 'mount /dev/blkdevice fmxa /mnt';
  dsh -c -mnode1,node2,node3...node<N> 'umount /mnt';
  where: <N> = 12, 24, or 48

Please let us know if Do you have any other test casss in mind?

ps. Please give us a week to reply as we're going to have public holidays in

Many thanks for looking so closely at the DLM and in sending this patch  
set. Some of the patches I can see are obvious fixes and others I'd need  
a bit more time to look at to be sure about. I've sent a few individual  
comments for some of the patches. However overall this looks like a  
really good set of patches, and I'm sure took some time for you to put  
together. I think the best thing would be for us to get these patches  
into a kernel now and run some tests, since there is quite a lot of change,
