Since "cifs: we do not need a spinlock around the tree access during umount" fixes "cifs: fix handlecache and multiuser" (commit 47178c7722ac528ea08aa82c3ef9ffa178962d7a) which was marked for stable. I marked "cifs: we do not need a spinlock around the tree access during umount" for stable as well. Let me know if you want me to change that. -- Thanks, Steve
