Subject: [musl] [PATCH 15/15] linux/syscalls.h: add missing __user annotations
Date: Thu, 20 Jun 2024 18:23:16 +0200	[thread overview]
Message-ID: <20240620162316.3674955-16-arnd@kernel.org> (raw)
In-Reply-To: <20240620162316.3674955-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

A couple of declarations in linux/syscalls.h are missing __user
annotations on their pointers, which can lead to warnings from
sparse because these don't match the implementation that have
the correct address space annotations.
