Yeah, my mess. Sorry.

A couple of people poked me about this issue last week. I merged the
patch without much scrutiny since several people had commented and
tested when it was originally posted a few months back. In looking over
the changes again, however, I agree with your assertion that it is
fishy.

My patch wasn't exclusively trying to address the regression wrt. drives
that temporarily come up read-only. Device or fabric events can also
trigger revalidate and there's a whole can of worms in that department
thanks to the intersection between device characteristics changing and
the partition table potentially being updated. This was my feeble
attempt at fixing several long-standing issues in the read-only device
handling which we occasionally hit.

I'll drop the offending patch and revert Jeremy's change for now. And
then revisit the gorge of eternal peril that is revalidate...
