Right, so what about cleaning that up first, then looking how many
workqueues can be removed by converting to threaded interrupts and then
maybe look again at some of your async things?

As to the SCSI/ATA error, have to wait for a year on hardware threads,
why not simply use the existing work to create a one-time (non-affine)
thread for that? Its not like it'll ever happen much.
