Subject: [PATCH 07/10] uapi: stddef.h: Introduce __kernel_nonstring
Date: Thu, 6 Feb 2025 17:00:16 -0800 [thread overview]
Message-ID: <20250207010022.749952-7-kees@kernel.org> (raw)
In-Reply-To: <20250207005832.work.324-kees@kernel.org>
In order to annotate byte arrays in UAPI that are not C strings (i.e.
they may not be NUL terminated), the "nonstring" attribute is needed.
However, we can't expose this to userspace as it is compiler version
specific.
