Subject: [Qemu-devel] [PULL 05/14] scsi-disk: fix bug in scsi_block_new_request() introduced by commit 137745c
Date: Wed, 18 Jun 2014 15:26:45 +0200	[thread overview]
Message-ID: <1403098014-1522-6-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1403098014-1522-1-git-send-email-pbonzini@redhat.com>

From: Ulrich Obergfell <uobergfe@redhat.com>

This patch fixes a bug in scsi_block_new_request() that was introduced
by commit 137745c5c60f083ec982fe9e861e8c16ebca1ba8. If the host cache
is used - i.e. if BDRV_O_NOCACHE is _not_ set - the 'break' statement
needs to be executed to 'fall back' to SG_IO.
