[SCSI] - fusion - mptfc bug fix's to prevent deadlock situations
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 Signed-off-by: Michael Reed <mdr@sgi.com> Signed-off-by: Eric Moore <Eric.Moore@lsil.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
