Subject: [PATCH 8/9] test: self: setjmp: make compatible with ASAN
Date: Mon, 25 Nov 2024 16:35:22 +0100	[thread overview]
Message-ID: <20241125153523.1411849-9-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20241125153523.1411849-1-a.fatoum@pengutronix.de>

ASAN currently flags the setjmp selftest. Use the newly exported fiber
API to fix this.
