Make DAMON sysfs interface to read the user inputs for DAMOS quota goals and pass those to DAMOS, so that the users can use the quota auto-tuning feature. It uses the DAMON sysfs interface's user input commit mechanism, which applies all user inputs for initial starting of DAMON and online input updates, which can be done by writing 'on' and 'commit' to the kdamond's 'state' file, respectively. In other words, the user should periodically write appropriate value to 'current_value' files and 'commit' command to the 'state' file. 'target_value' files could also be similarly updated at any time. Note that the interface is supporting multiple goals while the core logic supports only one goal. DAMON sysfs interface passes only best feedback among the given inputs, to avoid making DAMOS too aggressive.

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.
