From 205ef7961f781496366e0a93a4ec621ad3724bd7 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 21 Oct 2010 16:43:43 +0200 Subject: block: Allow bdrv_flush to return errors This changes bdrv_flush to return 0 on success and -errno in case of failure. It's a requirement for implementing proper error handle in users of bdrv_flush.
