SeongJae Park 6813131578 mm/damon/sysfs-schemes: implement quota effective_bytes file
DAMON sysfs interface allows users to set two types of quotas, namely time
quota and size quota.  DAMOS converts time quota to a size quota and use
smaller one among the resulting two size quotas.  The resulting effective
size quota can be helpful for debugging and analysis, but not exposed to
the user.  The recently added feedback-driven quota auto-tuning is making
it even more mysterious.

Implement a DAMON sysfs interface read-only empty file, namely
'effective_bytes', under the quota goal DAMON sysfs directory.  It will be
extended to expose the effective quota to the end user.

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.
