From f76c710d759250a43976bcfcab6af6ebb94b7dc2 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Fri, 13 Jun 2008 22:45:42 +0300 Subject: [PATCH] KVM: Use printk_rlimit() instead of reporting emulation failures just once Emulation failure reports are useful, so allow more than one per the lifetime of the module.
