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
