The problem here is dropping dir lock in posix_acl_create after getting
default_acl and acl. These two can be changed by another node by
the time we get around to using them in ocfs2_init_security_and_acl.
The old code in uek3 is mindful of this. In that code,
ocfs2_init_security_and_acl
gets the dir lock and keeps it until the acls of new node are set.
Thanks
