Another issue with <linux/export.h> is that it is sometimes included even when EXPORT_SYMBOL() is not used at all. Some headers (e.g. include/linux/linkage.h>) cannot be fixed for now for the reason described in the previous commit. This commit adds a warning for *.c files that include <linux/export.h> but do not use EXPORT_SYMBOL() when the kernel is built with W=1. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
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 reStructuredText 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.
