> "Resolve as you go" inode iteration will help with the implementation of alternative
locking schemes.  It will also be the pre-cursor for resolving paths once and only once per
operation, as opposed to ~3 times/call.
> This is an incremental and compatible change for IIP that does not break existing callers.
