From d916faace3efc0bf19fe9a615a1ab8fa1a24cd93 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Sun, 3 Dec 2006 22:22:41 -0500 Subject: Remove long-unmaintained ftape driver subsystem. It's bitrotten, long unmaintained, long hidden under BROKEN_ON_SMP, etc. As scheduled in feature-removal-schedule.txt, and ack'd several times on lkml.
