From 31ca020b57f7c08da187613cf20becd664c467fa Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 7 Mar 2013 15:55:49 +0100 Subject: [PATCH] TTY: wake up processes last at hangup Move wake up of processes on blocked-open and modem-status wait queues to after port shutdown at hangup. This way the woken up processes can use the ASYNC_INITIALIZED flag to detect port shutdown. Note that this is the order currently used by serial-core.
