Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
fd41e60331
When used on cgroup1, bfq uses the blkg->stat_bytes and ->stat_ios from blk-cgroup core to populate six stat knobs. blk-cgroup core is moving away from blkg_rwstat to improve scalability and won't be able to support this usage. It isn't like the sharing gains all that much. Let's break it out to dedicated rwstat counters which are updated when on cgroup1. This makes use of bfqg_*rwstat*() helpers outside of CONFIG_BFQ_CGROUP_DEBUG. Move them out. v2: Compile fix when !CONFIG_BFQ_CGROUP_DEBUG.

README
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.
