Subject: [PATCH v4 35/66] selftests/net: Drop define _GNU_SOURCE
Date: Fri, 10 May 2024 00:06:52 +0000	[thread overview]
Message-ID: <20240510000842.410729-36-edliaw@google.com> (raw)
In-Reply-To: <20240510000842.410729-1-edliaw@google.com>

_GNU_SOURCE is provided by lib.mk, so it should be dropped to prevent
redefinition warnings.
