From b8e660b83d505148c83ddc6d5ba69c29d0eab1e3 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 26 Feb 2010 22:37:41 +0100 Subject: [S390] Replace ENOTSUPP usage with EOPNOTSUPP ENOTSUPP is not supposed to leak to userspace so lets just use EOPNOTSUPP everywhere. Doesn't fix a bug, but makes future reviews easier.
