[Qemu-devel] [PATCH 04/34] scripts/kvm/kvm_stat: Removed unneeded PERF c


From: Janosch Frank
Subject: [Qemu-devel] [PATCH 04/34] scripts/kvm/kvm_stat: Removed unneeded PERF constants
Date: Thu, 10 Dec 2015 13:12:34 +0100

Only two of the constants are actually needed to set up the events, so
the others were removed. All variables that used them were also removed.
