      megaraid: fix BUG_ON() from incorrect use of delayed work · c1d390d8
      由 Xiaotian Feng 提交于 
      megaraid use INIT_WORK to declare a hotplug_work, but cast the
hotplug_work from work_struct to delayed_work and
schedule_delayed_work on it.  This is very dangerous, as other part of
delayed_work might be kernel memories allocated by others.

With commit 8852aac2 ("workqueue: mod_delayed_work_on() shouldn't queue
timer on 0 delay"), schedule_delayed_work() will check dwork->timer
before queue_work even when @delay is 0, this causes megaraid code to
hit the BUG_ON() in workqueue code.  Change megaraid code to use
delayed work.

      [SCSI] megaraid_sas: Add Online Controller Reset to MegaRAID SAS drive · 39a98554
      由 bo yang 提交于 
      To add the Online controller reset support, driver need to do:
a). reset the controller chips -- Xscale and Gen2 which will change
the function calls and add the reset function related to this two
chips.
b). during the reset, driver will store the pending cmds which not
returned by FW to driver's pending queue.  Driver will re-issue those
pending cmds again to FW after the OCR finished.
c). In driver's timeout routine, driver will report to OS as reset.
Also driver's queue routine will block the cmds until the OCR
finished.
d). in Driver's ISR routine, if driver get the FW state as state
change, FW in Failure status and FW support online controller
reset (OCR), driver will start to do the controller reset.
e). In driver's IOCTL routine, the application cmds will wait for the
OCR to finish, then issue the cmds to FW.
