From 1ecd3902c6e16c2445165b872c49e73770b72da7 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Mon, 15 Oct 2007 23:05:07 -0600 Subject: [SCSI] fc4: remove this and all associated drivers This code has been slowly rotting for about eight years. It's currently impeding a few SCSI cleanups, and nobody seems to have hardware to test it any more. I talked to Dave Miller about it, and he agrees we can delete it. If anyone wants a software FC stack in future, they can retrieve this driver from git. Signed-off-by: Matthew Wilcox Acked-by: David S.
