From 0b85b64d6b70b100f6222a96ff2337c302b386f1 Mon Sep 17 00:00:00 2001 From: Dmitry Vyukov Date: Mon, 22 May 2017 09:27:39 +0200 Subject: [PATCH] libstd/sync/mpsc: relicense under rust license These files are licensed under a different license than the rest of the codebase. This causes potential issues and inconveniences. Relicense these files under the standard license. I hold original copyright on that code.
