From f0ac2abcc0c7a3d148d32afed6f5e99692d54d2f Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 1 Jun 2018 20:35:10 +0200 Subject: [PATCH] ncpfs: remove compat functionality Now that ncpfs is gone from the tree, no need to have the compatibility thunking layer around, it will not actually go anywhere :) So delete that logic from fs/compat.c, it is no longer needed.
