Hi, The following patches add trace support in kvm using relay_fs and trace_mark according to last comments. if we want to use it, we should config kvm_trace firstly which depends on MARKERS and SYSFS, at this case it will add a tiny time penalty to check whether we provide a hook to call a function. if we don't config MARKERS, the trace functions are void. I refer to the blktrace code to implement it. Welcome comments.
