on a build of current master on el6.7 seeing a flood of reports in /var/log/messages like the following during sanity tests:

May 3 16:47:20 centos67-2 kernel: format at mdt_handler.c:1536:mdt_getattr_name_lock doesn't end in newline

Almost certain this is due to some recent change in master, as such messages haven't been seen before.
