/* XXX 2 bytes hole, try to pack */
__u32 flags; /* 20 4 */ __u64 preemption_timer_deadline; /* 24 8 */ };
Post-patch: struct kvm_vmx_nested_state_hdr { __u64 vmxon_pa; /* 0 8 */ __u64 vmcs12_pa; /* 8 8 */ struct { __u16 flags; /* 16 2 */ } smm; /* 16 2 */ __u16 pad; /* 18 2 */ __u32 flags; /* 20 4 */ __u64 preemption_timer_deadline; /* 24 8 */ };
