Subject: [PATCH v2 nolibc 14/15] tools/nolibc: add testcase for fork()/waitpid()
Date: Thu, 18 May 2023 07:55:20 -0700	[thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <4817a4dc-69e6-4937-84d5-f2f630ff646c@paulmck-laptop>

From: Thomas Weißschuh <[email protected]>

On s390 the arguments to clone() which is used by fork() are different
than other archs.
Make sure everything works correctly.
