DAMOS_MIGRATE_{HOT,COLD} can have multiple action destinations and their
weights. Implement sysfs directory named 'dests' under each scheme
directory to let DAMON sysfs ABI users utilize the feature. The interface
is similar to other multiple parameters directory like kdamonds or
filters. The directory contains only nr_dests file initially. Writing a
number of desired destinations to nr_dests creates directories of the
number. Each of the created directories has two files named id and
weight. Users can then write the destination's identifier (node id in
case of DAMOS_MIGRATE_*) and weight to the files.

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.
