It seems that "{0}" version is way more popular > over the mm code and in the kernel in general. Is there a downside to the comma? I'm finding more { 0, } than { 0 } in mm code, and at least kernel-wide it seems both are acceptable (although { 0 } is more popular overall). I don't care much either way. I can change it in v2 if there is one.
