2020-10-13scsi: handle zone resources errorsDamien Le Moal
ZBC or ZAC disks that have a limit on the number of open zones may fail a zone open command or a write to a zone that is not already implicitly or explicitly open if the total number of open zones is already at the maximum allowed. For these operations, instead of returning the generic BLK_STS_IOERR, return BLK_STS_ZONE_OPEN_RESOURCE which is returned as -ETOOMANYREFS to the I/O issuer, allowing the device user to act appropriately on these relatively benign zone resource errors.

2020-10-07scsi: pm80xx: Increase number of supported queuesViswas G
Current driver uses fixed number of Inbound and Outbound queues and all of the I/O, TMF and internal requests are submitted through those. A global spin lock is used to control the shared access. This can create a lock contention and it is real bottleneck in the I/O path. To avoid this, the number of supported Inbound and Outbound queues is increased to 64, and the number of queues used is decided based on number of CPU cores online and number of MSI-X vectors allocated. Also add locks per queue instead of using the global lock.

If an extra phy0 up happens during resume of the SAS controller, it will emit a new libsas event (event PORTE_BYTES_DMAED and event DISCE_DISCOVER_DOMAIN). We will call function scsi_sysfs_add_sdev() in event DISCE_DISCOVER_DOMAIN, which will call __pm_runtime_set_status() to resume supplier (host controller). For runtime PM core, if device is in the resuming state, the later resume request of the device will wait for previous resume request to complete synchronously. At that point in time the state of the controller is still resuming as it waits for all libsas events to be completed, while libsas event DISCE_DISCOVER_DOMAIN is blocked as the state of the controller is resuming which causes a deadlock. To avoid the issue, filter out new PHY up events while the controller is suspended.
