Current design has the fcloop job struct, used for both initiator and target processing, allocated as part of the initiator request structure. On aborts, the initiator side (based on the request) may terminate, yet the target side wants to continue processing. the target side can't do that if the initiator side goes away. Revise fcloop to allocate an independent target side structure when it starts an io from the initiator. Added a lock to the request struct as well to synchronize pointer updates on abort calls. Modified target downcalls to recognize conditions where initiator has aborted the io (thus nulled the pointer between job structs), thus avoid referencing sgl lists which are gone and no longer making upcalls to the initiator. In conditions where the targetport is no longer connected, have the initiator return an access failure rather than simulating a command completion.
