Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

Since it's BOOLEAN:

```suggestion:-0+0
            leap->enabled = TRUE;
```

Can you pull this FIXME out of this if statement so it's printed unconditionally?

(Otherwise, I'd like some tests for `STATUS_INFO_LENGTH_MISMATCH` case. Thanks!)

(That question mark was a typo, my apologies. Feel free to disregard this review, since I'm not maintaining here.)

[William Horvath (＠whrvth)]

I believe the case should also be added to `wow64_NtQuerySystemInformation`.

[Hans Leidekker (＠hans)]

Where did you find the SYSTEM_LEAP_SECOND_INFORMATION definition? It's not in the SDK I have here but perhaps there's a newer version.
