In the ongoing effort to replace all fake flexible arrays with true flexible arrays, replace the sge32, sge64, and sge_skinny members of union megasas_sgl with true flexible arrays. No binary differences are seen after this change; sizes were already being manually calculated using the member struct sizes directly.

Don Brace <don.brace@microchip.com> says: These patches are based on Martin Petersen's 6.4/scsi-queue tree https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git 6.4/scsi-queue This set of changes consists of: * Map entire BAR 0. The driver was mapping up to and including the controller registers, but not all of BAR 0. * Add PCI IDs to support new controllers. * Clean up some code by removing unnecessary NULL checks. This cleanup is a result of a Coverity report. * Correct a rare memory leak whenever pqi_sas_port_add_rhpy() returns an error. This was Suggested by: Yang Yingliang <yangyingliang@huawei.com> * Remove atomic operations on variable raid_bypass_cnt. Accuracy is not required for driver operation. Change type from atomic_t to unsigned int. * Correct a rare drive hot-plug removal issue where we get a NULL io_request. We added a check for this condition. * Turn on NCQ priority for AIO requests to disks comprising RAID devices. * Correct byte aligned writew() operations on some ARM servers. Changed the writew() to two writeb() operations. * Change how the driver checks for a sanitize operation in progress. We were using TEST UNIT READY. We removed the TEST UNIT READY code and are now using the controller's firmware information in order to avoid issues caused by drives failing to complete TEST UNIT READY. * Some customers have been requesting that we add the NUMA node to /sys/block/sd<scsi device>/device like the nvme driver does. * Update the copyright information to match the current year. * Bump the driver version to 2.1.22-040.

Pranav Prasad <pranavpp@google.com> says: This patch series enhances debug logs for pm80xx HW events, and provides a minor fix in the case of a hard reset. The log enhancement involves changing the log severity level to enable logging for HW events which consequently help debug disk discovery issues. 1. Changed log severity level from MSG to EVENT for HW events. Enhanced the HW event logs by adding the phyid. 2. Enabled INIT logging. 3. Log portid along with the PHY_UP event. 4. Print phyid and portid sent as part of device registration request. 5. Log port state during HW events. 6. Update phy_state and phy_attached to correct values after a hard reset.

Stop sending driver-initiated TURs to physical devices during driver load/rescan. Note: This does not affect SML initiated TURs. Some Linux kernels can cause lengthy delays in OS boot if the kernel detects that a drive is being sanitized/erased. We were using TURs to detect if a sanitize/erase was in progress. Some devices do not return the TUR in a timely manner, causing driver load/rescan stalls. Reviewed-by:

System crash due to use after free. Current code allows terminate_rport_io to exit before making sure all IOs has returned. For FCP-2 device, IO's can hang on in HW because driver has not tear down the session in FW at first sign of cable pull. When dev_loss_tmo timer pops, terminate_rport_io is called and upper layer is about to free various resources. Terminate_rport_io trigger qla to do the final cleanup, but the cleanup might not be fast enough where it leave qla still holding on to the same resource. Wait for IO's to return to upper layer before resources are freed. Cc: stable@vger.kernel.org Signed-off-by:

It has been determined that the threaded IRQ API accomplishes effectively the same performance metrics as blk_irq_poll.

Otherwise if ndlp has no rpi registered, the lpfc_nlp_put() at the end of lpfc_cmpl_els_logo_acc() is the final ndlp clean up.
