ocfs2_data_convert_worker() is currently dropping any cached acl info for FILE before down-converting meta lock. It should also drop for DIRECTORY. Otherwise the second acl lookup returns the cached one (from VFS layer) which could be already stale.
The problem we are seeing is that the acl changes on one node doesn't get refreshed on other nodes in the following case:
Node 1 Node 2 -------------- ---------------- getfacl dir1
getfacl dir1 <-- this is OK
setfacl -m u:user1:rwX dir1 getfacl dir1 <-- see the change for user1
getfacl dir1 <-- can't see change for user1
