From a15d5642a03a0b6c6cf327e497e688d1ba4c676d Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 17 Jun 2014 17:54:34 +1000 Subject: [PATCH] kvm_stat: Abstract ioctl numbers Unfortunately ioctl numbers are platform specific, so abstract them out of the code so they can be overridden. As it happens x86 and s390 share the same values, so nothing needs to change yet.
