According to [1], using directory lists ordered by inode can speed up
tar archivation by up to 40% on ext[34] filesystems (confirmed by my own
measurements). Please take a look at the attached patch. Is it OK
to apply?

New function streamsavedir_ordered returns directory
entries ordered by names or inode
Thanks for doing that. How about the attached (untested) patch
instead? It simplifies things by removing the obsolescent function
fdsavedir, and omitting the static variable that stores internal state.
