[win-pv-devel] [PATCH 2/2] Avoid PDO namespace conflicts...

[Paul Durrant <pdurrant@xxxxxxxxx>]

...by encoding the driver major version in the upper byte of the
revision.

This clearly implies that any future change in the driver major version
will start a new PDO namespace, but that it almost certainly the correct
thing to do in that case.
