The are terms that seem obvious to the mm developers, but may be somewhat obscure for, say, less involved readers. The concepts overview can be seen as an "extended glossary" that introduces such terms to the readers of the kernel documentation.

Memory Management

=================

|
|
|
Linux memory management subsystem is responsible, as the name implies,
|
|
for managing the memory in the system. This includes implemnetation of
|
|
virtual memory and demand paging, memory allocation both for kernel
|
|
internal structures and user space programms, mapping of files into
|
|
processes address space and many other cool things.
|
|
|
|
Linux memory management is a complex system with many configurable
|
|
settings. Most of these settings are available via ``/proc``
|
|
filesystem and can be quired and adjusted using ``sysctl``. These APIs
|
|
are described in Documentation/sysctl/vm.txt and in `man 5 proc`_.

|
|
Linux memory management has its own jargon and if you are not yet
|
|
familiar with it, consider reading
|
|
:ref:`Documentation/admin-guide/mm/concepts.rst <mm_concepts>`.
|
|
|
|
Here we document in detail how to interact with various mechanisms in
|
|
the Linux memory management.
