Bruno Prémont 975f7d4674 qla2xxx: fix busy wait regression ... Commit e05fe29248 (qla2xxx: Honor FCP_RSP retry delay timer field.) causes systems to busy-wait for about 3 minutes after boot prior to detecting SAN disks. During this wait period one kworker is running full-time (though /proc/<pid>/stack has no useful data). Another kworker is waiting for IO to complete during that whole time period. Looking at drivers/scsi/qla2xxx/qla_os.c, fcport->retry_delay_timestamp has a special value of 0 though that 0 value forces system to wait when jiffies is very large value (e.g. 4294952605 - "negative" value when signed on 32bit systems).
