it clearly makes a difference.

the unshare_files change causes init to no longer share the same fd table
with the other kernel threads. thus, when init closes or opens fds it does
not affect the other kernel threads. this patch allows init to continue to
share the same fd table with the other kernel threads as before the
unshare_files change. it does not compromise the intention of the
unshare_files change afaik.
