* Quoting an old commit message:miod2014-01-261-1/+2
| | | | | | ``Callers of scsi_iopool_init() ought to set up the pool member in struct scsi_link accordingly, for bad things will happen without (and this was a real pita to debug).''

| | | | | | | | | thing that stores state for luns. instead of checking and allocating it in the scsi_cmd path, and doing weird things all over the place to free it (eg, there's a timeout that ran every 10m to gc luns), use the scsi_probe and scsi_free things the midlayer calls.

| | | | | | | | | | | | such as READ_CAPACITY_16. So plugging SCSI-3 devices onto such a bus can be problematic. Cap the acceptable xs->cmdlen at 12 in ncr53c9x.c. Problem noted and fix tested by Kurt Mosiejczuk. Thanks! Diff mostly from miod@ with kibitzing from me. ok miod@

* Change the scsi_cmd function member of scsi_adapter from int tokrw2010-03-231-7/+15
| | | | | | | | | | | | | void. Use XS_NO_CCB error in the scsi command (xs) to report the NO_CCB condition. Eliminates all SUCCESSFULLY_QUEUED and COMPLETE confusion and untangles the midlayer from the adapter a bit more. Eyes and some fixes by miod@ There may be some compile issues on little used (i.e. I don't have any) drivers but the change is mechanical and thus easy to remedy. ok dlg@

* Bring last drivers fully into the NO_CCB world by replacingkrw2009-11-221-2/+2
| | | | | | | | | | | TRY_AGAIN_LATER uses with equivalent NO_CCB. Eliminates confusion between the two as was always intended. buf I/O's that can't be started get pushed back onto the front of the queue and retried. Others get sent back to originator as failures. No more epi-cycle looping inside the SCSI midlayer hoping the problem goes away. Various testers, no objection from miod@ as vs(4) was tested by nick@.

* Pool deals fairly well with physical memory shortage, but it doesn't dealart2002-01-231-2/+2
| | | | | | | | | | | | | | | | | | well (not at all) with shortages of the vm_map where the pages are mapped (usually kmem_map). Try to deal with it: - group all information the backend allocator for a pool in a separate struct. The pool will only have a pointer to that struct. - change the pool_init API to reflect that. - link all pools allocating from the same allocator on a linked list. - Since an allocator is responsible to wait for physical memory it will only fail (waitok) when it runs out of its backing vm_map, carefully drain pools using the same allocator so that va space is freed. (see comments in code for caveats and details). - change pool_reclaim to return if it actually succeeded to free some memory, use that information to make draining easier and more efficient. - get rid of PR_URGENT, noone uses it.
* Initialize variable before use. ok fgs@nordin2001-12-171-2/+2
