[PATCH BUGFIX 0/4] bfq: fix bugs breaking bandwidth guarantees occasionally

[Paolo Valente]

Hi,
during some bandwidth tests, I found some occasional but severe
malfunctions (losses of bandwidth control). The first three patches in
this series fix the bugs that caused these malfunctions. The last
patch is a fix/improvement of the name of one of the functions
involved with these bugs.

I guess these patches are appropriate for next kernel release.

Thanks,
Paolo
