Subject: [PATCH 08/16] KVM: MMU: change handle_abnormal_pfn() arguments to kvm_page_fault
Date: Sat, 7 Aug 2021 09:49:28 -0400 [thread overview]
Message-ID: <20210807134936.3083984-9-pbonzini@redhat.com> (raw)
In-Reply-To: <20210807134936.3083984-1-pbonzini@redhat.com>
Pass struct kvm_page_fault to handle_abnormal_pfn() instead of
extracting the arguments from the struct.
Suggested-by: Isaku Yamahata <isaku.yamahata@intel.com>
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
