aacraid.cache parameter, Disable Queue Flush commands:
bit 0 - Disable FUA in WRITE SCSI commands
bit 1 - Disable SYNCHRONIZE_CACHE SCSI command
bit 2 - Disable only if Battery not protecting adapter supplied Cache
e.g.: aacraid.cache=7 will disable the FUA and SYNCHRONIZE_CACHE
commands if the adapter has reported that it's cache is battery backed
up.
This parameter permits experimentation with tradeoffs between
performance and caching policy.
