Don Brace <don.brace@microchip.com> says: cat smartpqi_6.6_cover_letter These patches are based on Martin Petersen's 6.6/scsi-queue tree https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git 6.6/scsi-queue The biggest functional change to smartpqi is the addition of an abort handler. Some customers were complaining about I/O stalls to all devices when only one device is reset. Adding an abort handler helps to prevent I/O stalls to all devices. All of the reset of the patches are small changes to logging messages, MACRO and variable name changes, and one minor change for LUN assignments. This set of changes consists of: * smartpqi-add-abort-handler When a device reset occurs, the SML pauses I/O to all devices presented by a controller instance causing some performance issues. To only affect device with a problematic request, we added an abort handler. The abort handler is implemented by using a device reset, but I/O to the other devices is no longer affected. * smartpqi-refactor-rename-MACRO-to-clarify-purpose The MACRO SOP_RC_INCORRECT_LOGICAL_UNIT was used to check for a condition where a TMF was sent an incorrect LUN. We renamed this MACRO to SOP_TMF_INCORRECT_LOGICAL_UNIT for clarity. * smartpqi-refactor-rename-pciinfo-to-pci_info Change the pciinfo variable to pci_info to make more readable code. No functional changes. * smartpqi-simplify-lun_number-assignment We simplified the conditional expression used to populate LUN numbers for requests. * smartpqi-enhance-shutdown-notification Clarify controller cache flush errors. We added in more precise information to the cache flush informational message. No functional changes. * smartpqi-enhance-controller-offline-notification The driver can offline a controller for multiple reasons. We added a description of why these rare offline actions are taken. And a function to provide the specific details of the shutdown. * smartpqi-enhance-error-messages We added host🚌target:lun to messages emitted in our reset/abort handlers. No functional changes. * smartpqi-change-driver-version-to-2.1.24-046 Link: https://lore.kernel.org/r/20230824155812.789913-1-don.brace@microchip.com Signed-off-by: Martin K.
