description:
Hack for PR 44961: restore the prior "logic" pertaining to looking up /
to prevent a crash when attempting rename("/", "foo"). This is not really
what I want going forward and it may cause e.g. rmdir("blah/") to fail, so
if it causes trouble for anyone back it out. The right fix is going to have
to wait until the qemu/tcp_vtw problems I ran into last night get sorted out.
