From 18b9f67962eb890da0c053e04c3cf0e91871d4fa Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 14 Aug 2015 10:22:00 +1000 Subject: [PATCH] md-cluster: remove inappropriate try_module_get from join() md_setup_cluster already calls try_module_get(), so this try_module_get isn't needed. Also, there is no matching module_put (except in error patch), so this leaves an unbalanced module count.
