Kdamond is implemented as a periodical split-merge pattern, which will create and destroy regions possibly at high frequency (hundreds or even thousands of per sec), depending on the number of regions and aggregation period. In that case, kmalloc and kfree could bring speed and space overheads, which can be improved by using a private kmem cache.

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.
