Linux kernel source tree

Users can use /sys/kernel/debug/lru_gen to trigger proactive memory reclaim of a specified memcg. Currently, statistics such as pgrefill, pgscan and pgsteal will be updated to the /proc/vmstat system memory statistics. This will confuse some system memory pressure monitoring tools, making it difficult to determine whether pgscan and pgsteal are caused by system-level pressure or by proactive memory reclaim of some specific memory cgroup. Therefore, make this interface behave similarly to memory.reclaim. Update proactive memory reclaim statistics only to its memory cgroup.

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 reStructuredText 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.
