sym_entry::sym is (unsigned char *) instead of (char *) because kallsyms exploits the MSB for compression, and the characters are used as the index of token_profit array. However, it requires casting (unsigned char *) to (char *) in some places since standard library functions such as strcmp(), strlen() expect (char *). Introduce a new helper, sym_name(), which advances the given pointer by 1 and casts it to (char *). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
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.
