Examples with explicit leading whitespace: Good: \tif (lapic_in_kernel(vcpu) && \t\s\s\s\svcpu->arch.apic->lapic_timer.timer_advance_ns) \t\tkvm_wait_lapic_expire(vcpu); Bad: \tif (lapic_in_kernel(vcpu) && \t\s\s\s\svcpu->arch.apic->lapic_timer.timer_advance_ns) \t\s\s\s\skvm_wait_lapic_expire(vcpu);
