Subject: [Qemu-devel] [PATCH v3 25/29] iscsi: Set bs->request_alignment
Date: Fri, 17 Jan 2014 15:15:15 +0100 [thread overview]
Message-ID: <1389968119-24771-26-git-send-email-kwolf@redhat.com> (raw)
In-Reply-To: <1389968119-24771-1-git-send-email-kwolf@redhat.com>
From: Paolo Bonzini <pbonzini@redhat.com>
The iSCSI backend already gets the block size from the READ CAPACITY
command it sends. Save it so that the generic block layer gets it
too.
