Replace usages of the locally defined ABS() macro with calls to the canonical abs() from kernel.h and remove the old definitions of ABS() This change was originally motivated by two local definitions of the ABS (absolute value) macro that fail to parenthesize their parameter properly. This can lead to a bad expansion for low-precedence expression arguments. For example: ABS(1-2) currently expands to ((1-2) < 0 ? (-1-2) : (1-2)) which evaluates to -3. But the correct expansion would be ((1-2) < 0 ? -(1-2) : (1-2)) which evaluates to 1. Signed-off-by: Dan Gopstein <dgopstein@nyu.edu> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> |

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.
