Subject: [Qemu-devel] [RFC PATCH v1 2/5] pc-bios/s390-ccw: Remove duplicate blk_factor adjustment
Date: Wed, 26 Apr 2017 16:46:42 +0200 [thread overview]
Message-ID: <20170426144645.12476-3-farman@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170426144645.12476-1-farman@linux.vnet.ibm.com>
When using virtio-scsi, we multiply the READ(10) data_size by
a block factor twice when building the I/O. This is fine,
since it's only 1 for SCSI disks, but let's clean it up.
