From: Roland Dreier Date: Fri, 16 Nov 2012 16:06:16 +0000 (-0800) Subject: target: Fix handling of aborted commands X-Git-Tag: upstream/snapshot3+hdmi~6188^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3ea160b3e8f0de8161861995d9901f61192fc0b0;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git target: Fix handling of aborted commands - 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.
