Subject: [PATCH BUGFIX 0/3] three fixes for the function bfq_requests_merged

Hi Jens,
this series fixes three bugs in bfq_requests_merged. In more detail:

- two linked bugs, with the first (critical: wrong lock) hidden by the
  second (less critical: wrong check that made the body of the
  function not be executed at all)
- a rather minor bug: superflous code

Thanks,
Paolo
