03_scsi_requeue_use_scsi_retry_command_instead_of_scsi_queue_insert.patch
There are two users of scsi_queue_insert() left now. One in
scsi_softirq() and the other in scsi_eh_flush_done_q(). The
only additional functionality of scsi_queue_insert() used is
setting device_blocked on ADD_TO_MLQUEUE case in
scsi_softirq().
Open code device_blocked setting and replace
scsi_queue_insert() with scsi_retry_command() in both cases.
