Subject: [PATCH BUGFIX RESEND 0/4] bfq: fix bugs breaking bandwidth guarantees occasionally
Date: Mon, 25 Jun 2018 21:55:33 +0200 [thread overview]
Message-ID: <20180625195537.7769-1-paolo.valente@linaro.org> (raw)
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
