From c667aeacc16e0de9e205faa93f57121d6f691973 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Thu, 31 Dec 2015 10:29:00 +0100 Subject: [PATCH] s390: rename struct _lowcore to struct lowcore Finally get rid of the leading underscore. I tried this already two or three years ago, however Michael Holzheu objected since this would break the crash utility (again). However Michael integrated support for the new name into the crash utility back then, so it doesn't break if the name will be changed now. So finally get rid of the ever confusing leading underscore.
