See other reply, it's being posted soon, just haven't gotten there yet
and it wasn't ready.
It's a prep patch so we can call do_renameat2 and pass in a filename
instead. The intent is not to have any functional changes in that prep
patch. But once we can pass in filenames instead of user pointers, it's
usable from io_uring.
I'll post this as soon as I get around to it, it's been on the back
burner for the last month or so.
