-=================================
-Linux Security Module Development
-=================================
-
-Based on https://lkml.org/lkml/2007/10/26/215,
-a new LSM is accepted into the kernel when its intent (a description of
-what it tries to protect against and in what cases one would expect to
-use it) has been appropriately documented in ``Documentation/admin-guide/LSM/``.
-This allows an LSM's code to be easily compared to its goals, and so
-that end users and distros can make a more informed decision about which
-LSMs suit their requirements.
-
-For extensive documentation on the available LSM hook interfaces, please
-see ``include/linux/lsm_hooks.h`` and associated structures:
-
-.. kernel-doc:: include/linux/lsm_hooks.h
