Add low limit for cgroup and corresponding cgroup interface. To be consistent with memcg, we allow users configure .low limit higher than .max limit. But the internal logic always assumes .low limit is lower than .max limit. So we add extra bps/iops_conf fields in throtl_grp for userspace configuration. Old bps/iops fields in throtl_grp will be the actual limit we use for throttling. Signed-off-by: Shaohua Li <shli@fb.com> Signed-off-by: Jens Axboe <axboe@fb.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
