You can't know, but more up-to-date versions of ftape don't use it any
more.
I tried to push ftape-4.02 into recent v2.1 kernel some weeks ago, but
had no time to resent the thing a third of fourth time.
ftape-4.x supports certain kinds of parallel port tape drives, so it
would be nice to have in the v2.2 kernel. It also gets rid of kernel
level software compression which was a bad idea anyway and has
improved write error recovery, compared to all previous versions of
ftape.
I hope to be able to release a new version next week and thereby will
produce a new patch and send it to Linus.
Thanks for taking care
Claus
