That's not that big a deal; you can just use the expansion of
namei_simple* from vfs_lookup.c and get rid of the pathbuf logic. The
main point of those functions is to isolate struct nameidata and
NDINIT from random callers that don't need to fiddle with them
directly.

admittedly it's not 100% trivial, but I think maybe it's worthwhile,
so I'll leave the PR open for now until I or someone gets around to it.
