From e641c1e81e54fc14908ff6785ef7d51e42c2e1bb Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 4 Sep 2013 19:00:20 +0200 Subject: 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.
