      [SCSI] - fusion - mptfc bug fix's to prevent deadlock situations · 65207fed
      由 Moore, Eric 提交于 
      mptbase.h

	bump version number to 3.03.09

	remove unneeded flags
	define workq and remove old fc specific locks

mptbase.c

	initialize new lock and don't initialize two removed locks

mptscsih.c

	when firmware reports target is no longer there, return
        DID_REQUEUE for fc hosts so that i/o doesn't get killed until
        the transport has an opportunity to manage the loss via its
        dev loss timer

	when the "eh_abort" routine is called, check to see if the
        driver has the command or not before looking to see if a reset
        is pending.  James Smart and I talked about this and believe
        that the API for this routine is: if driver doesn't have
        command, return SUCCESS.  This change helps prevent a target
        from being taken offline.  SUCCESS is returned because it's
        likely that the command completed after error recovery timed
        it out but before it could be aborted.

	provide a routine to queue work to newly created workq, and
        use it.

	remove "ioc" from mptscsih_abort() it was only used one time.
	the other references were via hd->ioc, so I just moved it....
	net change in references to ioc via hd->ioc is zero

	move hd->resetPending test and hd->timeouts increment to after
	the test for whether the command to be aborted remains known
	to the driver

	Make certain that the workq exists before queuing work to it.

mptfc.c

	no longer need to lock rport data structures as I was able to
	single thread the code!  I fixed up the debug code to
	eliminate compilation messages due to type mismatch in the
	printk.  Got rid of some no longer needed rport flags.
	Initialize and destroy the workq used for the rescan work.

	simplify the logic regarding the increment of
        fc_rescan_work_count.  use post increment and test for zero
        vs. pre increment and test for one; eliminate work_count
        variable: queue_work can be called with the work_lock held as
        it doesn't sleep

      [SCSI] mptfusion: bug fix's for raid components adding/deleting · bd23e94c
      由 Moore, Eric 提交于 
      This patch handles case where raid hidden components
are not being removed when power turned off to device
attached to expander, as well as the case of
exposing raid components when power is turned back on
to devices attached to an expander.  (This is a repost
of this patch, with  mptsas_is_end_device declared
further up in the code.)

This patch contains some other miscellaneous bug fix's.

      [SCSI] mptspi: Add transport class Domain Validation · c92f222e
      由 James Bottomley 提交于 
      This is the first half of a patch to add the generic domain validation
to mptspi.  It also creates a secondary "virtual" channel for raid
component devices since these are now exported with no_uld_attach.

What Eric and I would have really liked is to export all physical
components on channel 0 and all raid components on channel 1.
Unfortunately, this would result in device renumbering on platforms with
mixed RAID/Physical devices which was considered unacceptable for
userland stability reasons.

Still to be done is to plug back the extra parameter setting and DV
pieces on reset and hotplug.
