I find this
_really_ helpful. It is great that you could build on top of existing
tracepoints but one thing is not entirely clear to me. Without a begin
marker in __alloc_pages_nodemask we cannot really tell how long the
whole allocation took, which would be extremely useful. Or do you use
any graph tracer tricks to deduce that?

Ia??m using the function graph tracer to see how long __alloc_pages_nodemask()
took.

How can you map the function graph tracer to a specif context? Let's say
I would like to know why a particular allocation took so long. Would
that be possible?
