• f309532bf   tty: Revert the tty locking series, it needs more work ... Browse Code »

  This reverts the tty layer change to use per-tty locking, because it's
  not correct yet, and fixing it will require some more deep surgery.

  The main revert is d29f3ef39be4 ("tty_lock: Localise the lock"), but
  there are several smaller commits that built upon it, they also get
  reverted here. The list of reverted commits is:

  fde86d310886 - tty: add lockdep annotations
  8f6576ad476b - tty: fix ldisc lock inversion trace
  d3ca8b64b97e - pty: Fix lock inversion
  b1d679afd766 - tty: drop the pty lock during hangup
  abcefe5fc357 - tty/amiserial: Add missing argument for tty_unlock()
  fd11b42e3598 - cris: fix missing tty arg in wait_event_interruptible_tty call
  d29f3ef39be4 - tty_lock: Localise the lock

  The revert had a trivial conflict in the 68360serial.c staging driver
  that got removed in the meantime.

  tty_lock_pair() do the right thing to avoid deadlocks, but should
  instruct LOCKDEP of this to avoid a splat.

  In each remaining case the tty_lock is associated with a specific tty. This
  means we can now lock on a per tty basis. We do need tty_lock_pair() for
  the pty case. Uglier but still a step in the right direction.

  We used it really only serial and ami_serial. The rest of the
  callsites were BUG/WARN_ONs to check if BTM is held. Now that we
  pruned tty_locked from both of the real users, we can get rid of
  tty_lock along with __big_tty_mutex_owner.

  The tty code should be in its own subdirectory and not in the char
  driver with all of the cruft that is currently there.
