Subject: [PATCH v3 0/2] optimize the bfq queue idle judgment
Date: Wed, 13 Oct 2021 19:25:32 +0800 [thread overview]
Message-ID: <20211013112534.3073296-1-yukuai3@huawei.com> (raw)
Changes in V3:
- Instead of tracking each queue in root group, tracking root group
directly just like non-root group does.
- remove patch 3,4 from these series.
Chagnes in V2:
- as suggested by Paolo, add support to track if root_group have any
pending requests, and use that to handle the situation when only one
group is activated while root group doesn't have any pending requests.
- modify commit message in patch 2
Yu Kuai (2):
block, bfq: counted root group into 'num_groups_with_pending_reqs'
block, bfq: do not idle if only one cgroup is activated
