Subject: [PATCH BUGFIX V2 0/7] block, bfq: series of fixes, and not only, for some recently reported issues

Hi Jens,
this the V2 of the series. The only change is the removal of ifdefs
from around gets and puts of bfq groups. As I wrote in my previous
cover letter, these patches are mostly fixes for the issues reported
in [1, 2]. All patches have been publicly tested in the dev version of
BFQ.

Thanks,
Paolo
