Subject: [PATCH 3/3] selftests/bpf: Define SYS_PREFIX for powerpc
Date: Mon, 4 Nov 2024 10:30:07 +0530 [thread overview]
Message-ID: <20241104050007.13812-4-skb99@linux.ibm.com> (raw)
In-Reply-To: <20241104050007.13812-1-skb99@linux.ibm.com>
SYS_PREFIX was missing for a powerpc, which made a kprobe test to
sys_prctl fail.
Add missing SYS_PREFIX for powerpc.
Fixes: 7e92e01b7245 ("powerpc: Provide syscall wrapper")
Fixes: 94746890202c ("powerpc: Don't add __powerpc_ prefix to syscall entry points")
