Subject: target: Use correct preempted registration sense code
From: Marco Sanvido <[email protected]>
commit 9e08e34e3735ae057eb3834da3570995811b7eb9 upstream.
The comments quote the right parts of the spec:
* d) Establish a unit attention condition for the
* initiator port associated with every I_T nexus
* that lost its registration other than the I_T
* nexus on which the PERSISTENT RESERVE OUT command
* was received, with the additional sense code set
* to REGISTRATIONS PREEMPTED.
and
* e) Establish a unit attention condition for the initiator
* port associated with every I_T nexus that lost its
* persistent reservation and/or registration, with the
* additional sense code set to REGISTRATIONS PREEMPTED;
but the actual code accidentally uses ASCQ_2AH_RESERVATIONS_PREEMPTED
instead of ASCQ_2AH_REGISTRATIONS_PREEMPTED. Fix this.
