strace shows this failure:

Also, this is what shows up in Procmon:

I should mention that I also cannot delete files with Windows 10 WSL. It
fails with that "Function not implemented" rather than "Invalid request
code", though it seems like it must be related.

PS C:\Windows\system32> wsl
sbaker AT FWA002495 /mnt/c/Windows/system32 $ rm -f /mnt/c/Test/test
rm: cannot remove '/mnt/c/Test/test': Function not implemented
