[PATCH v3 08/49] trace/kvm: Split address space and slot id in trace_kvm


From: Michael Roth
Subject: [PATCH v3 08/49] trace/kvm: Split address space and slot id in trace_kvm_set_user_memory()
Date: Wed, 20 Mar 2024 03:39:04 -0500

From: Xiaoyao Li <xiaoyao.li@intel.com>

The upper 16 bits of kvm_userspace_memory_region::slot are
address space id. Parse it separately in trace_kvm_set_user_memory().
