Its filename is slub-drop-lockdep_assert_held-from-put_map.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/slub-drop-lockdep_assert_held-from-put_map.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/slub-drop-lockdep_assert_held-from-put_map.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Sebastian Andrzej Siewior <bigeasy@linutronix.de> 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().
