Further in vt_ioctl, there is a call to vt_event_wait_ioctl which calls vt_event_wait and that calls wait_event_interruptible_tty which unlocks BTM. You change wait_event_interruptible_tty to wait_event_interruptible even in 4/6. The VT_WAITEVENT case should have tty_lock until 4/6 (and not longer). thanks, -- js suse labs -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
