Or rather it's a barrier(), which is anyway implied by rcu_read_lock(). So perhaps we can get rid of the IS_ENABLED() check?

Test monitoring on custom github repo

by Thomas Garnier

Hi, I am working on KASLR (PIE for x86_64). I previously used Kees (CCed) branches for lkp bot testing but someone told be I could ask you to add a custom github path to monitor all branches on it. I pushed my changes to: https://github.com/thgarnie/linux (kasrl_pie_v2 right now) Can you add it? Anything I need to do? Thanks, -- Thomas

d50d82faa0 [ 33.671845] WARNING: possible circular locking dependency detected

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master commit d50d82faa0c964e31f7a946ba8aba7c715ca7ab0 Author: Mikulas Patocka <mpatocka(a)redhat.com> AuthorDate: Wed Jun 27 23:26:09 2018 -0700 Commit: Linus Torvalds <torvalds(a)linux-foundation.org> CommitDate: Thu Jun 28 11:16:44 2018 -0700 slub: fix failure when we delete and create a slab cache In kernel 4.17 I removed some code from dm-bufio that did slab cache merging (commit 21bb13276768: "dm bufio: remove code that merges slab caches") - both slab and slub support merging caches with identical attributes, so dm-bufio now just calls kmem_cache_create and relies on implicit merging. This uncovered a bug in the slub subsystem - if we delete a cache and immediatelly create another cache with the same attributes, it fails because of duplicate filename in /sys/kernel/slab/. The slub subsystem offloads freeing the cache to a workqueue - and if we create the new cache before the workqueue runs, it complains because of duplicate filename in sysfs. This patch fixes the bug by moving the call of kobject_del from sysfs_slab_remove_workfn to shutdown_cache. kobject_del must be called while we hold slab_mutex - so that the sysfs entry is deleted before a cache with the same attributes could be created.

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://github.com/bbrezillon/linux-0day nand/cleanup commit 0babe16c6c4b5563ea0f6377363c220d4b3aa177 Author: Boris Brezillon <boris.brezillon(a)bootlin.com> AuthorDate: Thu Oct 25 17:10:37 2018 +0200 Commit: Boris Brezillon <boris.brezillon(a)bootlin.com> CommitDate: Tue Oct 30 09:26:53 2018 +0100 mtd: rawnand: Fill memorg during detection If we want to use the generic NAND layer, we need to have the memorg struct appropriately filled. Patch the detection code to fill this struct.
