Linux memory management subsystem is responsible, as the name implies,
|
2026-01-29 22:25:33 +08:00
|
|
|
for managing the memory in the system. This includes implementation of
|

|
|
|
virtual memory and demand paging, memory allocation both for kernel

|
|
|
internal structures and user space programs, mapping of files into

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/admin-guide/sysctl/vm.rst and in `man 5 proc`_.

Linux memory management has its own jargon and if you are not yet

|
|
|
familiar with it, consider reading Documentation/admin-guide/mm/concepts.rst.
