Saner locking around deactivate_super() Make sure that s_umount is acquired *before* we drop the final active reference; we still have the fast path (atomic_dec_unless) and we have gotten rid of the window between the moment when s_active hits zero and s_umount is acquired. Which simplifies the living hell out of grab_super() and inotify pin_to_kill() stuff. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
