From 9cf8bd529c6ba81402ebf6b7a56307b0787e4f93 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 15 Dec 2016 20:04:31 -0800 Subject: libnvdimm: replace mutex_is_locked() warnings with lockdep_assert_held For warnings that should only ever trigger during development and testing replace WARN statements with lockdep_assert_held. The lockdep pattern is prevalent, and these paths are are well covered by libnvdimm unit tests.
