scsi: smartpqi: fix time handling

2017-05-14T12:08:27+00:00

commit ed10858eadd4988260c6bc7d75fc25176342b5a7 upstream. When we have turned off RTC support, the smartpqi driver fails to build: ERROR: "rtc_time64_to_tm" [drivers/scsi/smartpqi/smartpqi.ko] undefined! This is easily avoided by using the generic 'struct tm' based helper rather than the RTC specific one. While fixing this, I noticed that even though the driver uses time64_t for storing seconds, it gets them from the old 32-bit struct timeval. To address this, we can simplify the code by calling ktime_get_real_seconds() directly.

scsi: smartpqi: switch to pci_alloc_irq_vectors

2016-11-08T22:30:00+00:00

Which cleans up a lot of the MSI-X handling, and allows us to use the PCI IRQ layer provided vector mapping, which we can then expose to blk-mq.

scsi: smartpqi: raid bypass lba calculation fix

2016-09-19T15:55:26+00:00

In the ioaccel path, the calculation of the starting LBA for READ(6)/WRITE(6) SCSI commands does not take into account the most significant 5 bits of the LBA: it only uses the least significant 16 bits of the starting LBA.

Some cache flush operations can take longer than the timeout value. Best to not impose a time limit to handle all cases.
