From 8b94ff85737062876c03e7506abb500521c749b9 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 20 Oct 2011 13:16:24 +0200 Subject: block: change flush to co_flush Since coroutine operation is now mandatory, convert all bdrv_flush implementations to coroutines. For qcow2, this means taking the lock. Other implementations are simpler and just forward bdrv_flush to the underlying protocol, so they can avoid the lock. The bdrv_flush callback is then unused and can be eliminated.
