In the lookup handler of a layered vfs, when and why should I be
using relookup instead of VOP_LOOKUP?

relookup looks just like a fat VOP_LOOKUP wrapper intend to implement
specific semantics, but the comment is rather minimal and there's
no relookup.9, so I'm discouraged from using it.  Aside from unionfs,
all the relookup consumers seem to be terminal layers.

Why/when should I use relookup?

Joshua
