Subject: [RFC PATCH tip 1/2] rseq selftests: Fix: use KHDR_INCLUDES for kernel headers
Date:   Mon, 16 Jan 2023 15:39:03 -0500
Message-Id: <20230116203904.214010-1-mathieu.desnoyers@efficios.com>
MIME-Version: 1.0

Precedence: bulk

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).
