Subject: [PATCH v2 0/2] xen-block: fix sector size confusion
Date: Wed, 27 Mar 2019 17:32:04 +0000 [thread overview]
Message-ID: <20190327173206.9065-1-paul.durrant@citrix.com> (raw)
The Xen blkif protocol is confusing but discussion with the maintainer
has clarified that sector based quantities in requests and the 'sectors'
value advertized in xenstore should always be in terms of 512-byte
units and not the advertised logical 'sector-size' value.
This series fixes xen-block to adhere to the spec.
Paul Durrant (2):
xen-block: scale sector based quantities correctly
xen-block: always report 'sectors' in terms of 512-byte units
