Message-Id: <20240212115500.2078463-14-max.kellermann@ionos.com>
Date: Mon, 12 Feb 2024 12:54:38 +0100
From: Max Kellermann <max.kellermann@...os.com>
To: linux-kernel@...r.kernel.org
Cc: Max Kellermann <max.kellermann@...os.com>
Subject: [PATCH v5 13/35] wait.h: move declarations to wait_types.h
By providing declarations in a lean header, we can reduce header
dependencies.
