Add intermediate STARGET_REMOVE state to scsi_target_state to avoid running into the BUG_ON() in scsi_target_reap(). The STARGET_REMOVE state is only valid in the path from scsi_remove_target() to scsi_target_destroy() indicating this target is going to be removed. This re-fixes the problem introduced in commits bc3f02a7 ("[SCSI] scsi_remove_target: fix softlockup regression on hot remove") and 40998193 ("scsi: restart list search after unlock in scsi_remove_target") in a more comprehensive way.

- On posting an IO to the firmware, adapter generates an interrupt. Due to hardware issues, sometimes the adapter fails to generate the interrupt. This behavior skips updating transmit queue- counters, which in turn causes the queue full condition. The fix addresses the queue full condition. - The fix also reserves a slot in transmit queue for hba reset. when queue full is observed during IO, there will always be room to post hba reset command.

When issuing I/O we check if rport is online through libfc rport_lookup() function which needs to be protected by mutex lock that cannot acquired in I/O context. The change is to use midlayer remote port s dd_data which is preserved until its devloss timeout and no protection is required.

If an I/O times out and an abort issued by host, if the abort is successful we need to set scsi status as DID_ABORT. Or else the mid-layer error handler which looks for this error code, will offline the device. Also if the original I/O is not found in fnic firmware, we will consider the abort as successful.

On larger installations it is useful to disable automatic LUN scanning, and only add the required LUNs via udev rules. This can speed up bootup dramatically. This patch introduces a new scan module parameter value 'manual', which works like 'none', but can be overridden by setting the 'rescan' value from scsi_scan_target to 'SCSI_SCAN_MANUAL'. And it updates all relevant callers to set the 'rescan' value to 'SCSI_SCAN_MANUAL' if invoked via the 'scan' option in sysfs. Signed-off-by: NHannes Reinecke <hare@suse.de> Reviewed-by: NEwan D.

I'm told that some targets are liable to disconnect a REQUEST SENSE command. Theoretically this would cause a command undergoing autosense to be moved onto the disconnected list. The bus reset handler must call complete_cmd() for these commands, otherwise the hostdata->sensing pointer will not get cleared. That would cause autosense processing to stall and a timeout or an incorrect scsi_eh_restore_cmnd() would eventually follow.

Fix various issues: Comments about bus errors are incorrect. The PDMA asm must return the size of the memory access that faulted so the transfer count can be adjusted accordingly. A phase change may cause a bus error but should not be treated as failure. A bus error does not always imply a phase change and generally the transfer may continue. Scatter/gather doesn't seem to work with PDMA due to overruns. This is a pity because peak throughput seems to double with SG_ALL. Tested on a Mac LC III and a PowerBook 520.

The benefit of limiting can_queue to 1 is that atari_scsi shares the ST DMA chip more fairly with other drivers (e.g. falcon-ide). Unfortunately, this can limit SCSI bus utilization. On systems without IDE, atari_scsi should issue SCSI commands whenever it can arbitrate for the bus. Make that possible by making can_queue configurable.
