@ajaygeorge can you please stamp this PR? Elliotte does not have committer status for presto-orc.

It's annoying that you can't merge this very simple and obviously correct and safe PR even though you are a committer on presto-orc. Really, presto is way too picky about who must stamp and approve what. Both Google and Meta have less stringent rules than this for their much larger and more diverse internal repositories, and it works just fine.
