- simplify the driver - there are a lot of quirky racy conditions not handled - causes more aborts/resets when the number of commands to be aborted is large, such as in multi-path fail-overs. - has been turned off in our internal driver since 8/31/2015 Reviewed-by:

- Block I/O requests with 0 length transfers which go down the ioaccel path. This causes lockup issues down in the basecode. - These issues have been fixed, but there are customers who are experiencing the issues when running older firmware. Reviewed-by:

create new worker thread to monitor controller events - both the rescan and event monitor workers can cause a rescan to occur however for multipath we have found that we need to respond faster than the normal scheduled rescan interval for path fail-overs. - getting controller events only involves reading a register, but the rescan worker can obtain an updated LUN list when there is a PTRAID device present. - move common code to a separate function. advantages: - detect controller events more frequently. - leave rescan thread interval at 30 seconds.
