Thanks Bart, so tying this back to Alex's patches, does the
ordering
problem that Alex's patches solve impact the SCSI case? I'm looking
for something like "SCSI depends on asynchronous probing and without
'driver core: Establish clear order of operations for deferred probe
and remove' probing is often needlessly serialized". I.e. does it
suffer from the same platform problem that libnvdimm ran into where
it's local async probing implementation was hindered by the driver
core?

Hi Dan,
Patch 6/9 reduces the time needed to scan SCSI LUNs significantly. The only
way to realize that speedup is by enabling more concurrency. That's why I
think that patch 6/9 is a significant driver core improvement.
Bart.
