From c80c3c269011c67b8dabef5238af44a6d94e4d0e Mon Sep 17 00:00:00 2001 From: David Ahern Date: Fri, 20 Jul 2012 17:25:51 -0600 Subject: [PATCH] perf kvm: Limit repetitive guestmount message to once per directory After 7ed97ad use of the guestmount option without a subdir for *each* VM generates an error message for each sample related to that VM. Once per VM is enough.
