From f530b531fb9e05eb134cfc334242799ea974d111 Mon Sep 17 00:00:00 2001 From: Mathias Krause Date: Fri, 17 Feb 2023 20:33:36 +0100 Subject: [PATCH] KVM: Shrink struct kvm_mmu_memory_cache Move the 'capacity' member around to make use of the padding hole on 64 bit systems instead of introducing yet another one. This allows us to save 8 bytes per instance for 64 bit builds of which, e.g., x86's struct kvm_vcpu_arch has a few.
