From f958d58a6a98cbc111c4e3eb58a4170ce725a915 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Fri, 3 Sep 2021 16:33:21 +0200 Subject: score: Split up rbtreenext.c Split up rbtreenext.c since only _RBTree_Minimum() is used by the operating system core services (thread queues and the EDF scheduler). Change license to BSD-2-Clause according to file history and re-licensing agreement.
