Subject: qla2xxx: Look up LUN for abort requests
From: Steve Hodgson <[email protected]>
commit 06e97b489006f28e23bb028febfa1c01c266d676 upstream.
Search through the list of pending commands on the session list to find
the command the initiator is actually aborting, so that we can pass the
correct LUN to the core TMR handling code.
(nab: Allow abort requests to work to LUN=0 with mainline target code)
