From 44f4641073f132429e1e9a53412600206e8f7d06 Mon Sep 17 00:00:00 2001 From: Martin Brandenburg Date: Mon, 15 Aug 2016 11:38:36 -0400 Subject: orangefs: clean up debugfs globals Mostly this is moving code into orangefs-debugfs.c so that globals turn into static globals. Then gossip_debug_mask is renamed orangefs_gossip_debug_mask but keeps global visibility, so it can be used from a macro.
