Subject: switch blk-cgroup to work on gendisk
Date: Tue, 17 Jan 2023 09:12:42 +0100 [thread overview]
Message-ID: <20230117081257.3089859-1-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.
