Please spell it out. I guess we could do is_guest_mode() like we do is_long_mode(). > + > +static inline bool kvm_vcpu_is_gm(struct kvm_vcpu *vcpu) > +{ > + return !!(vcpu->arch.hflags& HF_GUEST_MASK); > +} > + !! unneeded with bool. Note we need to live migrate this bit, but that's outside the scope of this patchset. -- error compiling committee.c: too many arguments to function
