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.

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.

in __scsi_add_device, sdev may be uninitialised if
scsi_host_scan_allowed() returns false. Fix by initialising at the
top of the routine. Also rely on the fact that
scsi_probe_and_add_lun() only actually fills in the sdev pointer if

For ATAPI commands, padding can reduce qc->n_elem by one and thus to

fail for legal commands. This patch fixes the assert()'s to take

Although the condition check seems a bit excessive, as this part of

There's a bug in releasing scsi_device where the release function
actually frees the block queue. However, the block queue release
calls flush_work(), which requires process context (the scsi_device
structure may release from irq context). Update the release function
to invoke via the execute_in_process_context() API.
Also clean up the scsi_target structure releasing via this API.

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. Unfortunately, it
requires memory allocation in interrupt context, but it's better than
what we have previously. The true solution will require a bit of
re-engineering, so isn't appropriate for 2.6.16.
