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.
