    Description

      This is split out from KUDU-2721. The issue is that this code https://github.com/apache/kudu/blob/148a0c7bec6554724339a2235cbd723fb74be339/src/kudu/gutil/sysinfo.cc#L177 only inspects /present, not /possible, so could return a result that becomes incorrect when a CPU is hotplugged.
