[Xen-devel] [PATCH 4 of 6] xen: sched: introduce a couple of counters in credit2 and SEDF

[Dario Faggioli <dario.faggioli@xxxxxxxxxx>]

Mainly for consistency with credit, at least for the events that are
general enough, like vCPU initialization/destruction and calls
to the specific scheduling function.
