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 Paolo Valente (4): block, bfq: add/remove entity weights correctly block, bfq: do not expire a queue that will deserve dispatch plugging block, bfq: fix service being wrongly set to zero in case of preemption block, bfq: fix service being wrongly set to zero in case of preemption block/bfq-iosched.c | 131 +++++++++++++++++++++++++++++++++++++++++++--------- block/bfq-iosched.h | 7 ++- block/bfq-wf2q.c | 30 ++++++------ 3 files changed, 128 insertions(+), 40 deletions(-) -- 2.16.1
