Based on the discussion about the signed character field for the year, I went through all fields in the iso9660 and rockridge standards to see whether they should used signed or unsigned characters. Only a single 8-bit value is defined as signed per 'section 7.1.2': the timezone offset in a timestamp, this has always been handled correctly through explicit sign-extension. All others are either '7.1.1 8-bit unsigned numerical values' or composite fields. I also read the linux source code and came to the same conclusion, also I could not find any other part of the implementation that actually behaves differently for signed or unsigned values. Since it is still ambigous to use plain 'char' in interface definitions, I'm changing all fields representing numbers and reserved bytes to the unambiguous '__u8'. Fields that hold actual strings are left as 'char' arrays. I built the code with '-Wpointer-sign -Wsign-compare' to see if anything got left out, but couldn't find anything wrong with the remaining warnings. This patch should not change runtime behavior and does not need to be backported. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jan Kara <jack@suse.cz> |

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
