From 3f1a1b7cbb94f5f61d55f5f8d7391a0d84824cca Mon Sep 17 00:00:00 2001 From: Lars Ellenberg Date: Tue, 29 Aug 2017 10:20:41 +0200 Subject: drbd: fix rmmod cleanup, remove _all_ debugfs entries If there are still resources defined, but "empty", no more volumes or connections configured, they don't hold module reference counts, so rmmod is possible. To avoid DRBD leftovers in debugfs, we need to call our global drbd_debugfs_cleanup() only after all resources have been cleaned up.
