Kernel-doc currently expects that the kernel-doc markup to come just before the function/enum/struct/union/typedef prototype. Yet, if it find things like: /** * refcount_add - add a value to a refcount * @i: the value to add to the refcount * @r: the refcount */ static inline void __refcount_add(int i, refcount_t *r, int *oldp); static inline void refcount_add(int i, refcount_t *r); Kernel-doc will do the wrong thing: foobar.h:6: warning: Function parameter or member 'oldp' not described in '__refcount_add' .. c:function:: void __refcount_add (int i, refcount_t *r, int *oldp) add a value to a refcount **Parameters** ``int i`` the value to add to the refcount ``refcount_t *r`` the refcount ``int *oldp`` *undescribed* Basically, it will document "__refcount_add" with the kernel-doc markup for refcount_add. If both functions have the same arguments, this won't even produce any warning! Add a logic to check if the kernel-doc identifier matches the actual name of the C function or data structure that will be documented.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
