From 050f99b1b85876a8456b76ebfee7d43746d37f6c Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 13 Mar 2017 15:58:35 +0100 Subject: [PATCH] s390/debugfs: introduce top-level 's390' directory Introduce a top-level 's390' directory which should be used when adding new s390 specific debug feature files and/or directories. This makes hopefully sure that the contents of the s390 directory will be a bit more structured. Right now we have a couple of top-level files where it is not easy to tell to which subsystem they belong to.
