Subject: [Qemu-devel] [PATCH 1/2] block/vdi: Don't ignore immediate read/write failures
Date: Sat, 19 Feb 2011 22:18:11 +0100 [thread overview]
Message-ID: <1298150292-16158-1-git-send-email-weil@mail.berlios.de> (raw)
This patch is similar to 171e3d6b9997c98a97d0c525867f7cd9b640cadd
which fixed qcow2:
Returning -EIO is far from optimal, but at least it's an error code.
