damon_call() can be useful for reading or writing DAMON internal data for one time. A common pattern of DAMON core usage from DAMON modules is doing such reads and writes repeatedly, for example, to periodically update the DAMOS stats. To do that with damon_call(), callers should call damon_call() repeatedly, with their own delay loop. Each caller doing that is repetitive. Introduce a repeat mode damon_call(). Callers can use the mode by setting a new field in damon_call_control. If the mode is turned on, damon_call() returns success immediately, and DAMON repeats invoking the callback function inside the kdamond main loop.

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.
