Subject: [PATCH v2 5/8] selftests: vDSO: vdso_test_gettimeofday: Use types from vdso_types.h
Date: Thu, 03 Sep 2026 09:38:17 +0200 [thread overview]
Message-ID: <20260903-vdso-test-types-v2-5-1eec04eb3658@linutronix.de> (raw)
In-Reply-To: <20260903-vdso-test-types-v2-0-1eec04eb3658@linutronix.de>
The libc types are not necessarily compatible with the vDSO functions.
Use the dedicated types from vdso_types.h instead.
