[git pull][vfs.git] a couple of fixes

	A couple of fixes; one for automount/lazy umount race, another
a classic "we don't protect the refcount transition to zero with the
lock that protects looking for object in hash" kind of crap in lockd.
Please, pull.  The usual place -
git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus

Shortlog:
Al Viro (2):
      do_add_mount()/umount -l races
      close the race in nlmsvc_free_block()

Hmm. What is the status of the rename_lock write-lock recursion
deadlock patch from Miklos?

Attached is a simpler version of it (Miklos, can you verify this
simplified version also works for you?), but it's still fairly ugly.
