Subject: [PATCH 12/16] KVM: MMU: change tdp_mmu_map_handle_target_level() arguments to kvm_page_fault
Date: Sat,  7 Aug 2021 09:49:32 -0400	[thread overview]
Message-ID: <20210807134936.3083984-13-pbonzini@redhat.com> (raw)
In-Reply-To: <20210807134936.3083984-1-pbonzini@redhat.com>

Pass struct kvm_page_fault to tdp_mmu_map_handle_target_level() instead of
extracting the arguments from the struct.
