The patch titled
     Subject: mm/slub.c: drop lockdep_assert_held() from put_map()
has been removed from the -mm tree.  Its filename was
     slub-drop-lockdep_assert_held-from-put_map.patch

This patch was dropped because it was merged into mainline or a subsystem tree

Subject: mm/slub.c: drop lockdep_assert_held() from put_map()

There is no point in using lockdep_assert_held() unlock that is about to
be unlocked.  It works only with lockdep and lockdep will complain if
spin_unlock() is used on a lock that has not been locked.

Remove superfluous lockdep_assert_held().
