The difference w.r.t. v2 are new fixes to the patch "block, bfq: print SHARED instead of pid for shared queues in logs", after patient checks and suggestions by Holger and Oleksandr. Thanks, Paolo Francesco Pollicino (2): block, bfq: print SHARED instead of pid for shared queues in logs block, bfq: save & resume weight on a queue merge/split Paolo Valente (7): block, bfq: increase idling for weight-raised queues block, bfq: do not idle for lowest-weight queues block, bfq: tune service injection basing on request service times block, bfq: do not merge queues on flash storage with queueing block, bfq: do not tag totally seeky queues as soft rt block, bfq: always protect newly-created queues from existing active queues doc, block, bfq: add information on bfq execution time Documentation/block/bfq-iosched.txt | 29 +- block/bfq-cgroup.c | 3 +- block/bfq-iosched.c | 786 +++++++++++++++++++++++----- block/bfq-iosched.h | 92 ++-- block/bfq-wf2q.c | 2 +- 5 files changed, 729 insertions(+), 183 deletions(-) --- 2.20.1
