The Linux kernel user-space API guide
=====================================

.. _man-pages: https://www.kernel.org/doc/man-pages/

While much of the kernel's user-space API is documented elsewhere
(particularly in the man-pages_ project), some user-space information can
also be found in the kernel tree itself.  This manual is intended to be the
place where this information is gathered.
