Subject: [PATCH v2 4/8] selftests: vDSO: vdso_test_abi: Use system call wrappers from vdso_syscalls.h
Date: Thu, 03 Sep 2026 09:38:16 +0200	[thread overview]
Message-ID: <20260903-vdso-test-types-v2-4-1eec04eb3658@linutronix.de> (raw)
In-Reply-To: <20260903-vdso-test-types-v2-0-1eec04eb3658@linutronix.de>

Using syscall(SYS_getcpu) is problematic for the reasons outlined in
vdso_syscalls.h.

Use the wrappers from the utility header instead.
