Subject: [PATCH BUGFIX/IMPROVEMENT 0/6] block, bfq: first bath of fixes and improvements
Date: Fri, 22 Jan 2021 19:19:42 +0100 [thread overview]
Message-ID: <20210122181948.35660-1-paolo.valente@linaro.org> (raw)
Hi,
about nine months ago, Jan (Kara, SUSE) reported a throughput
regression with BFQ. That was the beginning of a fruitful dev&testing
collaboration, which led to 18 new commits. Part are fixes, part are
actual performance improvements.
Jia Cheng Hu (1):
block, bfq: set next_rq to waker_bfqq->next_rq in waker injection
Paolo Valente (5):
block, bfq: use half slice_idle as a threshold to check short ttime
block, bfq: increase time window for waker detection
block, bfq: do not raise non-default weights
block, bfq: avoid spurious switches to soft_rt of interactive queues
block, bfq: do not expire a queue when it is the only busy one
