McKenney" Cc: Mark Brown , linux-kernel@vger.kernel.org, Willy Tarreau Subject: [PATCH 03/42] tools/nolibc/std: move the standard type definitions to std.h Date: Mon, 7 Feb 2022 17:23:15 +0100 Message-Id: <20220207162354.14293-4-w@1wt.eu> X-Mailer: git-send-email 2.17.5 In-Reply-To: <20220207162354.14293-1-w@1wt.eu> References: <20220207162354.14293-1-w@1wt.eu> Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org The ordering of includes and definitions for now is a bit of a mess, as for example asm/signal.h is included after int defintions, but plenty of structures are defined later as they rely on other includes. Let's move the standard type definitions to a dedicated file that is included first. We also move NULL there. This way all other includes are aware of it, and we can bring asm/signal.h back to the top of the file.
