SMPConfiguration and CpuTopology have named fields so we could drop the
'expect: ...' comment line and instead do
{
/* no configuration provided */
.config = { .has_cpus = F, .has_maxcpus = F, ... },
.valid = T,
.expect = { .sockets = 1, .cores = 1, ... },
}, {
...
}
which may be easier to maintain. OTOH, the concise form this approach has
is also nice. I don't think you should need the casts in the assignments
though.
