The devfreq subsystem has plenty of kernel-doc comments but they're not currently included in sphinx documentation. Add a minimal devfreq.rst file which mostly just includes kernel-doc comments from devfreq source. This also exposes a number of kernel-doc warnings on `make htmldocs` Signed-off-by: Leonard Crestez <leonard.crestez@nxp.com> Link: https://lore.kernel.org/r/e32fa9de8a60060a6ee5fc42f163111034f9a550.1574181341.git.leonard.crestez@nxp.comSigned-off-by: Jonathan Corbet <corbet@lwn.net>

While checking the results of the :c:func: removal, I noticed that there was no documentation for request_irq(), and request_threaded_irq() was not mentioned at all. Add a kerneldoc comment for request_irq() and add request_threaded_irq() to the list of functions. Reviewed-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

The second paragraph of the content section does not properly describe how mount points are determined by autofs.

Convert autofs.txt to reST. The following changes abound: - Introduce reST formatting for headings, lists et al. - Add an indentation of an 8 space tab wherever suitable, so as to maintain consistency. - Remove indentation of the description of the ioctls which are similar to the AUTOFS_IOC ioctls, as it does not come out quite right in HTML. - Add an entry for autofs in the index.

One of the recurring complaints from both maintainers and CI system operators is that performing git-am on received patches is difficult without knowing the parent object in the git history on which the patches are based. Without this information, there is a high likelihood that git-am will fail due to conflicts, which is particularly frustrating to CI operators. Git versions starting with v2.9.0 are able to automatically include base-commit information using the --base flag of git-format-patch. Document this usage in process/submitting-patches, and add the rationale for its inclusion, plus instructions for those not using git on where the "base-commit:" trailer should go.

The 'functions' directive is not only for functions, but also works for structs/unions. So the name is misleading. This patch renames it to 'identifiers', which specific the functions/types to be included in documentation. We keep the old name as an alias of the new one before all documentation are updated.

Jonathan Neuschäfer authored
Currently, when kernel-doc encounters a macro with a named variable argument[1], such as this: #define hlist_for_each_entry_rcu(pos, head, member, cond...) ... it expects the variable argument to be documented as `cond...`, rather than `cond`. This is semantically wrong, because the name (as used in the macro body) is actually `cond`. With this patch, kernel-doc will accept the name without dots (`cond` in the example above) in doc comments, and warn if the name with dots (`cond...`) is used and verbose mode[2] is enabled. The support for the `cond...` syntax can be removed later, when the documentation of all such macros has been switched to the new syntax. Testing this patch on top of v5.4-rc6, `make htmldocs` shows a few changes in log output and HTML output: 1) The following warnings[3] are eliminated: ./include/linux/rculist.h:374: warning: Excess function parameter 'cond' description in 'list_for_each_entry_rcu' ./include/linux/rculist.h:651: warning: Excess function parameter 'cond' description in 'hlist_for_each_entry_rcu' 2) For list_for_each_entry_rcu and hlist_for_each_entry_rcu, the correct description is shown 3) Named variable arguments are shown without dots [1]: https://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html [2]: scripts/kernel-doc -v [3]: See also https://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git/commit/?h=dev&id=5bc4bc0d6153617eabde275285b7b5a8137fdf3cSigned-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> Tested-by: Paul E.
