Hi List,
I would appreciate if some one can help me out on these.
1) Suppose my machine has two similar SCSI HBAs. And my Linux box shows them
to me as Hosts 0 and 1 respectively. When I open the chassis, is a there a
way to figure out that physically which of the HBAs I am seeing correspond
01_scsi_no_REQ_SPECIAL_on_requeue.patch
blk_insert_request() has 'reinsert' argument, which, when set,
turns on REQ_SPECIAL and REQ_SOFTBARRIER and requeues the
request. SCSI midlayer was the only user of this feature and
all requeued requests become special
04_scsi_remove_volatile.patch
scsi_device-device_busy, Scsi_Host-host_busy and
-host_failed have volatile qualifiers, but the qualifiers
don't serve any purpose. Kill them. While at it, protect
-host_failed update in scsi_error for consistency and clarity.
11_scsi_make_requeue_command_public.patch
Add reprep argument to scsi_requeue_command(), remove
redundant q argument, add code to set cmd-state/owner, and
make the function public. This patch is preparation for
consolidating requeue paths.
Signed-off-by: Tejun
12_scsi_consolidate_requeue_paths.patch
Add scsi_device_unbusy() call to scsi_retry_command(), replace
scsi_queue_insert() with scsi_requeue_command(), make
scsi_softirq() use scsi_retry_command() for ADD_TO_MLQUEUE
case too (with explicit device blocking), and

Markus, is this patch actually okay? I just talked to Andi about the
ioctl32 issues and he told me about this patch.

Hi Bryan,
Thanks for the reply. I got my queries solved.
As with other SCSI numbering (LUNs, Linux device numbers),
you normally don't try to prescribe which numbers go to which
equipment, but rather discover afterward --
