Subject: [ 09/27] target: Fix handling of aborted commands
Date: Thu, 6 Dec 2012 16:58:53 -0800 [thread overview]
Message-ID: <20121207005828.262252687@linuxfoundation.org> (raw)
In-Reply-To: <20121207005825.232489605@linuxfoundation.org>
3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Roland Dreier <roland@purestorage.com>
commit 3ea160b3e8f0de8161861995d9901f61192fc0b0 upstream.
- If we stop processing an already-aborted command in
target_execute_cmd(), then we need to complete t_transport_stop_comp
to wake up the the TMR handling thread, or else it will end up
waiting forever.
- If we've a already sent an "aborted" status for a command in
transport_check_aborted_status() then we should bail out of
transport_send_task_abort() to avoid freeing the command twice.
