erk. I was rather expecting I'd have time to have a look at it all.

It's unclear to me actually _why_ the performance changes which were
observed have actually occurred. In fact it's a bit unclear (to me)
why the patchset was written and what it sets out to achieve :(

A long time ago the XFS guys (Dave Chinner iirc) said that XFS needs
more than one thread per device to keep the device saturated. Did that
get addressed?

(kthread_run() returns an ERR_PTR() on error, btw - not NULL.)
