2006-03-02[SCSI] qla2xxx: use kthread_ APIChristoph Hellwig6-74/+38
Use the kthread_ API instead of opencoding lots of hairy code for kernel thread creation and teardown. Also switch from semaphore-based thread wakeup to wake_up_process.

2006-03-01[SCSI] mptspi: Add transport class Domain ValidationJames Bottomley6-2459/+774
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. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-02-27[SCSI] fix scsi process problems and clean up the target reap issuesJames Bottomley5-77/+46
In order to use the new execute_in_process_context() API, you have to provide it with the work storage, which I do in SCSI in scsi_device and scsi_target, but which also means that we can no longer queue up the target reaps, so instead I moved the target to a state model which allows target_alloc to detect if we've received a dying target and wait for it to be gone. Hopefully, this should also solve the target namespace race. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-02-27[SCSI] add execute_in_process_context() APIJames Bottomley2-0/+35
We have several points in the SCSI stack (primarily for our device functions) where we need to guarantee process context, but (given the place where the last reference was released) we cannot guarantee this. This API gets around the issue by executing the function directly if the caller has process context, but scheduling a workqueue to execute in process context if the caller doesn't have it.

2006-02-27[SCSI] don't call ips_eh_reset in ips_queue to avoid deadlockMike Christie1-1/+1
When the locking was changed in the eh code ips_eh_reset was changed so that it was a wraper around __ips_eh_reset and all ips_eh_reset does is grab the host lock and then calls __ips_eh_reset. In the queuecommand, ips_queue is called with the host_lock held so if it calls ips_eh_reset we will have a problem. This patch just has ips_queue call __ips_eh_reset. Patch is only compile tested. I do not have the HW. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Acked-by: Hammer, Jack <Jack_Hammer@adaptec.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-02-27[SCSI] Recognize missing LUNs for non-standard devicesAlan Stern2-1/+17
Some non-standard SCSI targets or protocols, such as USB UFI, report "no LUN present" by setting the Peripheral Device Type to 0x1f and the Peripheral Qualifier to 0 (not 3 as the standard requires) in the INQUIRY response. This patch (as650b) adds a new target flag and code to accomodate such targets. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

New version that switches to the common onstack completion and just a pointer in the platform_data struct idiom. This gets rid of all the flags fiddling.

Also rely on the fact that scsi_probe_and_add_lun() only actually fills in the sdev pointer if the SCSI_SCAN_LUN_PRESENT case (so no need to check the return value).
