Hi, all!
I'm planning to support build all blk-throttle polices as kernel module,
this is the first part for blk-throttle:
- patch 1 remove THROTTLE LOW;
- patch 2 delay initialization from disk initialization to
configuration;
- patch 3-5 support to destroy blk-throttle is it's disabled;
- patch 6 switch blk-throttle to use rq_qos to stop exposing
blk-throttle internal implementations;
Changes from RFV v1:
- add missing places in patch 1;
- add patch 2-6;
Yu Kuai (6):
blk-throttle: remove CONFIG_BLK_DEV_THROTTLING_LOW
blk-throttle: delay initialization until configuration
blk-throttle: expand tg_conf_updated() to return if any tg has rules
blk-cgroup: add a new helper blkg_conf_exit_blkg()
blk-throttle: support to destroy throtl_data when blk-throttle is
disabled
blk-throtl: switch to use rq_qos
