From c4f907719736b720aa831447828809840e533371 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 21 May 2018 14:35:12 +1000 Subject: staging: lustre: make lnet_debugfs_symlink_def local to libcfs/modules.c This type is only used in libcfs/module.c, so make it local to there. If any other module ever wanted to add its own symlinks, it would probably be easiest to export lnet_debugfs_root and just call debugfs_create_symlink as required.
