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`_.
