Ram Pai 70fbcdf4d2 [PATCH] umount_tree() locking change
umount is done under the protection of the namespace semaphore.  This
can lead to intresting deadlocks when the last reference to a mount is
released, if filesystem code is in sufficiently nasty state.

This collects all the to-be-released-mounts and releases them after
releasing the namespace semaphore.  That both reduces the time we are
holding namespace semaphore and gets the things more robust.

Idea proposed by Al Viro.
