[Ocfs2-users] issues with my ocfs2 cluster

Changwei explained to me that 4.4.0 did not have the bug that he was
referencing with 4.4.9.
I would consider using 4.4.10. I just need to be wary of breaking anything
in the openstack/kvm infrastructure by making a kernel change.

the most recent occurrence of this spin lock I definitely know there were
no servers in the cluster that were rebooted or lost power...

thanks
