Subject: [git pull] vfs fix

	Fix for very unpleasant braino in do_umount(); the effect was
that if umount(name, MNT_EXPIRE) failed with -EBUSY it left the kernel
with doubly-taken vfsmount_lock.  The next attempt to mount or umount
something would deadlock, of course...  Please, pull from

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ for-linus

J. R. Okajima (1):
      Unlock vfsmount_lock in do_umount
