When "make tags", it prompts a warning:
ctags: Warning: drivers/pci/controller/pcie-apple.c:150:
null expansion of name pattern "\1"
The reason is that there is an indentation beside arguments of
DECLARE_BITMAP, but it can parsed normally by gtags. It's also
allowed in C.
Regex [:space:] can match any white space character, so it's a
better approach to add it to each item in regex_c.

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.
