  * done.  Cleanup is just deactivate_super().  However, that leaves a messy
  * case - what if we *are* racing with umount() and active references to
  * superblock can't be acquired anymore?  We can bump ->s_count, grab
- * ->s_umount, which will almost certainly wait until the superblock is shut
- * down and the watch in question is pining for fjords.  That's fine, but
- * there is a problem - we might have hit the window between ->s_active
- * getting to 0 (i.e. the moment when superblock is past the point of no return
- * and is heading for shutdown) and the moment when deactivate_super() acquires
- * ->s_umount.  We could just do drop_super() yield() and retry, but that's
- * rather antisocial and this stuff is luser-triggerable.  OTOH, having grabbed
- * ->s_umount and having found that we'd got there first (i.e. that ->s_root is
- * non-NULL) we know that we won't race with inotify_umount_inodes().  So we
- * could grab a reference to watch and do the rest as above, just with
- * drop_super() instead of deactivate_super(), right?  Wrong.  We had to drop
- * ih->mutex before we could grab ->s_umount.  So the watch could've been gone
- * already.
- *
- * That still can be dealt with - we need to save watch->wd, do idr_find()
- * and compare its result with our pointer.  If they match, we either have
- * the damn thing still alive or we'd lost not one but two races at once,
- * the watch had been killed and a new one got created with the same ->wd
- * at the same address.  That couldn't have happened in inotify_destroy(),
- * but inotify_rm_wd() could run into that.  Still, "new one got created"
- * is not a problem - we have every right to kill it or leave it alone,
- * whatever's more convenient.
- *
- * So we can use idr_find(...) == watch && watch->inode->i_sb == sb as
- * "grab it and kill it" check.  If it's been our original watch, we are
- * fine, if it's a newcomer - nevermind, just pretend that we'd won the
- * race and kill the fscker anyway; we are safe since we know that its
