src/lib/libc/include/spinlock.h, branch releng/12.4 FreeBSD source tree https://cgit-dev.freebsd.org/src/atom?h=releng%2F12.4 2017-11-20T19:49:47Z General further adoption of SPDX licensing ID tags. 2017-11-20T19:49:47Z Pedro F. Giffuni pfg@FreeBSD.org 2017-11-20T19:49:47Z urn:sha1:8a16b7a18f5d0b031f09832fd7752fba717e2a97 Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Remove old spinlock_debug code from libc 2017-05-20T17:32:01Z Eric van Gyzen vangyzen@FreeBSD.org 2017-05-20T17:32:01Z urn:sha1:07f29d9f76cf7c3879c223ae0a7d7d5fab3bfd2c This no longer seems useful. Remove it. This was prompted by a "cast discards volatile qualifier" warning in libthr when WARNS=6.
