Wei Yang 3ff519f29d KVM: x86: adjust kvm_mmu_page member to save 8 bytes ... On a 64bits machine, struct is naturally aligned with 8 bytes. Since kvm_mmu_page member *unsync* and *role* are less then 4 bytes, we can rearrange the sequence to compace the struct. As the comment shows, *role* and *gfn* are used to key the shadow page. In order to keep the comment valid, this patch moves the *unsync* up and exchange the position of *role* and *gfn*. From /proc/slabinfo, it shows the size of kvm_mmu_page is 8 bytes less and with one more object per slap after applying this patch. # name <active_objs> <num_objs> <objsize> <objperslab> kvm_mmu_page_header 0 0 168 24 kvm_mmu_page_header 0 0 160 25 Signed-off-by: Wei Yang <richard.weiyang@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>		2018-10-17 00:29:40 +02:00
