Then we would have to determine what the scenarios are. The problem is to cover
all interesting instrumentation mixes efficiently.
I think it could be a good enough list :
Fprobes only
Dynamic + Fprobes (supports dynamic probes and uses fprobes for non probable
code)
Dynamic only
Printk only
Which would be expressed in the following menu :
choice Marker behavior
* Inactive
* Dynamic probes
* Function probes (Fprobes)
* Dynamic probes complemented with Fprobes
* Printk
if selected "Dynamic probes" or "Dynamic probes complemented with Fprobes"
choice2 Dynamic probes behavior
* Kprobes
* Jprobes
Any thoughts ?
Mathieu
