      lock_parent() needs to recheck if dentry got __dentry_kill'ed under it · 3b821409
      Al Viro authored
      In case when dentry passed to lock_parent() is protected from freeing only
      by the fact that it's on a shrink list and trylock of parent fails, we
      could get hit by __dentry_kill() (and subsequent dentry_kill(parent))
      between unlocking dentry and locking presumed parent.  We need to recheck
      that dentry is alive once we lock both it and parent *and* postpone
      rcu_read_unlock() until after that point.  Otherwise we could return
      a pointer to struct dentry that already is rcu-scheduled for freeing, with
      ->d_lock held on it; caller's subsequent attempt to unlock it can end
      up with memory corruption.
