Remove the pointless task_req_upiu and task_rsp_upiu indirections, which are __le32 arrays always cast to given structures and just add the members directly. Also clean up variables names in use in the callers a bit to make the code more readable. Signed-off-by:

lockdep_assert_held() is better suited to checking locking requirements, since it won't get confused when someone else holds the lock. This is also a step towards possibly removing spin_is_locked(). Signed-off-by:

The SR_RST bit isn't latched. Hence, detecting a bus reset isn't reliable. When it is detected, the right thing to do is to drop all connected and disconnected commands. The code for that is already present so refactor it and call it when SR_RST is set. Tested-by:

The X3T9.2 specification (draft) says, under "6.1.4.2 RESELECTION time-out procedure", that a target may assert RST or go to BUS FREE phase if the initiator does not respond within 200 us. Something like this has been observed with AztecMonster II target. When it happens, all we can do is wait for the target to try again. Tested-by:

The X3T9.2 specification (draft) says, under "6.1.4.1 RESELECTION", ... The reselected initiator shall then assert the BSY signal within a selection abort time of its most recent detection of being reselected; this is required for correct operation of the time-out procedure. The selection abort time is only 200 us which may be insufficient time for a printk() call. Move the diagnostics to the error paths. Tested-by:

When NCR5380_abort() returns FAILED, the driver forgets that the target is still busy. Hence, further commands may be sent to the target, which may fail during selection and produce the error message, "reselection after won arbitration?". Prevent this by leaving the busy flag set when NCR5380_abort() fails. Tested-by:

When the lldd is processing the complete sas task in interrupt and set the task stat as SAS_TASK_STATE_DONE, the smp timeout timer is able to be triggered at the same time. And smp_task_timedout() will complete the task wheter the SAS_TASK_STATE_DONE is set or not. Then the sas task may freed before lldd end the interrupt process. Thus a use-after-free will happen. Fix this by calling the complete() only when SAS_TASK_STATE_DONE is not set. And remove the check of the return value of the del_timer(). Once the LLDD sets DONE, it must call task->done(), which will call smp_task_done()->complete() and the task will be completed and freed correctly. Reported-by:

When ata device IDENTIFY failed, the ata device status is ATA_DEV_UNKNOWN. The libata reported like: [113518.620433] ata5.00: qc timeout (cmd 0xec) [113518.653646] ata5.00: failed to IDENTIFY (I/O error, err_mask=0x4) But libsas verifies the device status by ata_dev_disabled(), which skipped ATA_DEV_UNKNOWN. This will make libsas think the ata device probing succeed the device cannot be actually brought up. And even the new bcast of this device will be considered as flutter and will not probe this device again. Change ata_dev_disabled() to !ata_dev_enabled() so that libsas can deal with this if the ata device probe failed. New bcasts can let us try to probe the device again and bring it up if it is fine to IDENTIFY. Tested-by:
