It may happen that destination buffer memory overlaps with memory dynptr points to. Hence, we must use memmove to correctly copy from dynptr to destination buffer, or source buffer to dynptr. This actually isn't a problem right now, as memcpy implementation falls back to memmove on detecting overlap and warns about it, but we shouldn't be relying on that.

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.
