src/include/stdbool.h, branch releng/12.4

include: General further adoption of SPDX licensing ID tags.

2017-11-25T17:09:43Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Remove unneeded guard.

There is no reason why needs an include guard. It is already protected by __bool_true_false_are_defined.

- Define true and false in sys/types.h for _KERNEL consumers, and

typedef bool. Due to macro expansion it seemed better to use a typedef for kernel consumers (specifically ofed won't compile without more changes if a define is used). - should also not re-define bool/true/false if they are defined by . It would probably be a programming error to define _KERNEL for user-space code, but downstream consumers like Isilon have already been including in kernel sources, and this protects that usage. - sizeof(_Bool) is not necessarily the same as sizeof(int), so kernel modules should be rebuild with this change.

Welcome stdbool.h. A header file from the ANSI C99 specification.

It defines the boolean values.
