Subject: [PATCH v3 0/5] blk-wbt: simple improvment to enable wbt correctly
Date: Thu, 22 Sep 2022 19:35:53 +0800 [thread overview]
Message-ID: <20220922113558.1085314-1-yukuai3@huawei.com> (raw)
changes in v3:
- instead of check elevator name, add a flag in elevator_queue, as
suggested by Christoph.
- add patch 3 and patch 5 to this patchset.
changes in v2:
- define new api if wbt config is not enabled in patch 1.
Yu Kuai (5):
wbt: don't show valid wbt_lat_usec in sysfs while wbt is disabled
elevator: add new field flags in struct elevator_queue
block, bfq: don't disable wbt if CONFIG_BFQ_GROUP_IOSCHED is disabled
blk-wbt: don't enable throttling if default elevator is bfq
elevator: remove redundant code in elv_unregister_queue()
