      devpts: more pty driver interface cleanups · 8ead9dd5
      Linus Torvalds 提交于
      This is more prep-work for the upcoming pty changes.  Still just code
      cleanup with no actual semantic changes.
      
      This removes a bunch pointless complexity by just having the slave pty
      side remember the dentry associated with the devpts slave rather than
      the inode.  That allows us to remove all the "look up the dentry" code
      for when we want to remove it again.
      
      Together with moving the tty pointer from "inode->i_private" to
      "dentry->d_fsdata" and getting rid of pointless inode locking, this
      removes about 30 lines of code.  Not only is the end result smaller,
      it's simpler and easier to understand.
      
      The old code, for example, depended on the d_find_alias() to not just
      find the dentry, but also to check that it is still hashed, which in
      turn validated the tty pointer in the inode.
      
      That is a _very_ roundabout way to say "invalidate the cached tty
      pointer when the dentry is removed".
      
      The new code just does
      
      	dentry->d_fsdata = NULL;
      
      in devpts_pty_kill() instead, invalidating the tty pointer rather more
      directly and obviously.  Don't do something complex and subtle when the
      obvious straightforward approach will do.
      
      The rest of the patch (ie apart from code deletion and the above tty
      pointer clearing) is just switching the calling convention to pass the
      dentry or file pointer around instead of the inode.
