And in particular the only locking change that I can see at all is that
d_walk takes read_seqbegin_or_lock before checking the if the d_subdirs
list is empty, which is just an extra cache line read.

Which in practical terms appears like I have removed unnecessary special
cases in favor less code. Which I think if anything should perform
better just because there is less code to run, and what is happening is
less obfuscated.
