Subject: [PATCH] KVM: x86: Fix Xen hypercall tracepoint argument assignment
Date: Tue, 12 May 2026 09:53:13 +0800 [thread overview]
Message-ID: <20260512015313.1685784-1-maqianga@uniontech.com> (raw)
TRACE_EVENT(kvm_xen_hypercall) stores a5 in __entry->a4 instead of
__entry->a5.
That overwrites the recorded a4 argument and leaves a5 unset in the
trace entry. Fix the typo so both arguments are captured correctly.
