Subject: switch blk-cgroup to work on gendisk v2
Date: Tue, 24 Jan 2023 07:57:00 +0100 [thread overview]
Message-ID: <20230124065716.152286-1-hch@lst.de> (raw)
Hi all,
blk-cgroup works on only on live disks and "file system" I/O from bios.
This all the information should be in the gendisk, and not the
request_queue that also exists for pure passthrough request based
devices.
Changes since v1:
- use the local disk variable in wbt_init instead of q->disk
- various spelling fixes
