Subject: [PATCH 0/2] scsi: libsas: Drop SAS_TASK_AT_INITIATOR

Apart from some isci driver code, flag SAS_TASK_AT_INITIATOR is only set,
so drop usage in that driver and then everywhere else.

This solves a use-after-free in the pm8001 queue path.

John Garry (2):
  scsi: isci: Drop SAS_TASK_AT_INITIATOR check in isci_task_abort_task()
  scsi: libsas: Drop SAS_TASK_AT_INITIATOR
