In fact, I think it would clean up prepend_path() and make it more
legible to have the two layers of mount_lock / rename_lock be done in
callers with the restarting being done as a loop in the caller rather
than as "goto restart_*".

Potentiallty delicate question is how to pass bptr/blen to the caller
of that helper...
