Subject: [PATCH v2 08/13] missing: move sys_execveat() to missing.h
Date: Thu, 12 May 2022 18:52:45 +0200	[thread overview]
Message-ID: <20220512165250.450989-9-brauner@kernel.org> (raw)
In-Reply-To: <20220512165250.450989-1-brauner@kernel.org>

The missing.h header provides syscalls potentially missing from the used
libc. Move the sys_execveat() definition into it. It doesn't belong into
vfstest.c.
