When kdamond_fn() completes, the targets are kept. Those are kept to let callers do additional cleanups if they need. There are no such additional cleanups though. DAMON sysfs interface deallocates those in before_terminate() callback, to reduce unnecessary memory usage, for [f]vaddr use case. Just destroy the targets for every case in the core layer. This saves more memory and simplifies the logic.

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.
