Subject: [PATCH v3 06/33] docs: cgroup-v1/blkio-controller.rst: add a note about CFQ scheduler
Date: Sat, 8 Jun 2019 23:26:56 -0300 [thread overview]
Message-ID: <6a36af686f9517d362c28424cfd0d3bd1729155b.1560045490.git.mchehab+samsung@kernel.org> (raw)
In-Reply-To: <cover.1560045490.git.mchehab+samsung@kernel.org>
The CFQ scheduler was removed on this changeset:
commit f382fb0bcef4c37dc049e9f6963e3baf204d815c
Author: Jens Axboe <axboe@kernel.dk>
Date: Fri Oct 12 10:14:46 2018 -0600
block: remove legacy IO schedulers
Retain the deadline documentation, as that carries over to mq-deadline
as well.
Tested-by: Ming Lei <ming.lei@redhat.com>
Reviewed-by: Omar Sandoval <osandov@fb.com>
Signed-off-by: Jens Axboe <axboe@kernel.dk>
However, the cgroups-v1 documentation still mentions it and points
to a removed file that used to belong to such scheduler.
Add a note about that, as someone needs to fix the document pointing
to another scheduler, if cgroups-v1 blockio is not dependent of
CFQ scheduler.
