Hey everyone,
I just found out from Steven over in GFS2 that there is a kernel
call forget_all_cached_acls(). If a cluster filesystem is using ACL
caching (added by Viro a little while back), they use
forget_all_cached_acls() at lock drop time to make sure they don't have
stale ACL info.
We're not using cached_acls yet, but if someone adds it, please
remember this call ;-)
Joel

I remembered that Jeff did some work on it when I was at Oracle.
So Jeff, did you still work on it now?

I have wrote a patch for catched acl about one and half year ago just for fun.
That patch has been tested on OCFS2 single node at that time, I will try it on cluster environment with this call.
Thanks,
