Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.

After commit dfd6200a ("blk-cgroup: support to track if policy is online"), there is no need to do this again in bfq. However, 'pd->online' is not protected by 'bfqd->lock', in order to make sure bfq won't see that 'pd->online' is still set after bfq_pd_offline(), clear it before bfq_pd_offline() is called. This is fine because other polices doesn't use 'pd->online' and bfq_pd_offline() will move active bfqq to root cgroup anyway. Signed-off-by:Yu Kuai <yukuai3@huawei.com> Reviewed-by:
