From adb26c09f26e34324e25f5947e3615f6e686ee34 Mon Sep 17 00:00:00 2001 From: Dario Faggioli Date: Tue, 23 Oct 2012 04:18:22 -0700 Subject: [PATCH] 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.
