Any interest in this or should I just table it for >= v3.14?
Sorry, I've been busy putting out another fire. Yes, there's definitely
still interest. I grabbed your revised patch and tested with it.
Unfortunately the timeout doesn't actually fire when requests are queued
due to queue_if_no_path; IIRC the block request queue timeout logic
wasn't triggering. I planned to look into it more deeply figure out why
but I had to spend all last week fixing a nasty race and hadn't gotten
back to it yet.
OK, Hannes, any idea why this might be happening? The patch in question
is here: https://patchwork.kernel.org/patch/3070391/
Not yet; currently I'm on vacation, but will be looking into it on Monday.
Cheers,
Hannes
