Extract the code that's specific for the "node" -numa option type (the only one, today) to a separate function.
The extracted code will eventually become a function specific for a "numa-node" config section, independent from the numa_add() code.

strtoull() needs additional error checking after the fact, to make sure I didn't pass an empty string, trailing garbage, or so many digits I triggered overflow.

More uses of strtoull() that aren't guarding against all possible errors. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
