Patch series "mm/damon: build-enable essential DAMON components by
default".
As of this writing, multiple major distros including Alma, Amazon,
Android, CentOS, Debian, Fedora, and Oracle are build-enabling DAMON (set
CONFIG_DAMON[1]). Configuring DAMON is not very easy, since it is
disabled by default, and there are multiple essential options that need to
be manually turned on, one by one. Make it easier, by grouping essential
configurations to be enabled with one selection, and enabling build of the
essential parts of DAMON by default.
Note that build-enabling DAMON does not introduce any real risk, since it
makes no behavioral change by default. It requires explicit user requests
to do anything. Only one potential risk is making the size of the kernel
a little bit larger. On a production-purpose configuration, it increases
the resulting kernel package binary size by about 0.1 % of the final
package file. I believe that's too small to be a real problem in common
setups.
DAMON_{VADDR,PADDR,SYSFS} are de-facto essential parts of DAMON for normal
usages. Because those need to be enabled one by one, however, and there
are other test-purpose or non-essential configurations, it is easy to be
confused and make mistakes at setup. Make the essential configurations
default to CONFIG_DAMON, so that those can be enabled by default with a
single change.

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.
