Implement the code for filling the data of 'tried_regions' DAMON sysfs directory. With this commit, DAMON sysfs interface users can write a special keyword, 'update_schemes_tried_regions' to the corresponding 'state' file of the kdamond. Then, DAMON sysfs interface will collect the tried regions information using the 'before_damos_apply()' callback for one aggregation interval and populate scheme region directories with the values. [sj@kernel.org: skip tried regions update if the scheme directory was removed] Link: https://lkml.kernel.org/r/20221114182954.4745-2-sj@kernel.org Link: https://lkml.kernel.org/r/20221101220328.95765-5-sj@kernel.org Signed-off-by: SeongJae Park <sj@kernel.org> Cc: Jonathan Corbet <corbet@lwn.net> Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
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.
