Is there any good reason for defining things this way, as opposed to a simple enumeration?
A simple enum would eliminate the need for

in patch 5.

Agreed. A simple enum would be much nicer. I was just following the
previous definition of
PRIV_VERSION_1_10_0 & PRIV_VERSION_1_11_0.

I am not sure about the reason behind this scheme.

@Alistair Francis <alistair.francis@wdc.com> Is there any history behind
this scheme ?
or Are you okay if I change it ?
