Subject: [PATCH 7/8] liblockdep: Fix 'defined but not used' warning for
 init_utsname()

From: Ben Hutchings <ben@...adent.org.uk>

We define init_utsname() as static but not inline, resulting
in a warning for every source file that includes lockdep.h but
doesn't call it.

Since it is only used by lockdep.c, define it in there.
