It's an elegant option, given the values are almost uniformly
tightly packed. It also saves a fair bit of space - around 2.5Kb.

For my taste, I do like being able to visually verify the
correctness of any given member. That way whenever I look at it, I
don't have to blindly trust that the list was previously set up
correctly, or count the lines to check if a given value is correct.
Not a big deal, but it does introduce some friction.

We could also use a designated initializer list:

static const char *hv_hypervisor_counters[] = {
	[1] = "HvLogicalProcessors",
	[2] = "HvPartitions",
	[3] = "HvTotalPages",
	[4] = "HvVirtualProcessors",
	[5] = "HvMonitoredNotifications",
	[6] = "HvModernStandbyEntries",
	[7] = "HvPlatformIdleTransitions",
	[8] = "HvHypervisorStartupCost",

	[10] = "HvIOSpacePages",
	...
};

The indices are explicit, so it's easy to visually verify that any
particular part of the list is correct. It's functionally identical
to your approach, so it saves the same amount of space, and the
explicit NULLs are unnecessary so it's more straightforward to
transform from the Windows source in case of any gaps that are
harder to notice later on in the list.

How does that sound?
