A profile like https://perfht.ml/2DRNa0O from bug 1527879 has lots of "create/open" markers without filename. To figure out what was happening I had to debug locally.
It turns out we do have the filename in the interposer at https://searchfox.org/mozilla-central/rev/b2d35912da5b2acecb0274eb113777d344ffb75e/xpcom/build/PoisonIOInterposerWin.cpp#134 but we don't save it because NtPathToDosPath returns false for these paths that don't exist.
