Subject: [PATCH BUGFIX V2 0/1] block, bfq: deschedule empty bfq_queues not referred by any process

Hi Jens,
change from V1: added check to correctly work only on bfq-queues
scheduled for service, and not on in-service bfq-queues (it makes no
sense, and it creates inconsistencies, to deschedule an in-service
bfq-queue).

Differently from V1, which was still under test when I submitted it,
this version has already been tested, by those who reported V1's
failures.

Thanks,
Paolo
