Subject: [PATCH] lib/interval-tree: add header guard in interval_tree_generic.h
Date: Sat, 15 Feb 2025 02:37:39 +0000 [thread overview]
Message-ID: <20250215023739.19809-1-richard.weiyang@gmail.com> (raw)
Per my understanding, we usually define header guard to prevent multiple
definition.
Let's add it as usual.
