From 38e889607fa438121b82a3ad81365fa113c1a279 Mon Sep 17 00:00:00 2001 Message-Id: <38e889607fa438121b82a3ad81365fa113c1a279.1379425497.git.minovotn@redhat.com> In-Reply-To: References: From: Paolo Bonzini Date: Fri, 6 Sep 2013 18:12:29 +0200 Subject: [PATCH 09/25] cow: do not call bdrv_co_is_allocated As we change bdrv_is_allocated to gather more information from bs and bs->file, it will become a bit slower. It is still appropriate for online jobs, but not for reads/writes. Call the internal function instead.
