From b3cb9fc3aeaf9d52967c87d54a98f035e96279dc Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Thu, 6 Aug 2020 23:19:09 -0700 Subject: [PATCH] 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().
