# HG changeset patch # User Dario Faggioli <dario.faggioli@xxxxxxxxxx> # Date 1350991102 25200 # Node ID 4ae12a96ec697f942600a78057bcb567f3312dca # Parent af87fb17adf38fcf8b2aec38356d9bc8cdcf3ebd xen: sched: introduce a couple of counters in credit2 and SEDF 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.
