Subject: [test_power_init] WARNING: CPU: 1 PID: 1 at lib/debugobjects.c:263
debug_print_object()
Hi Anton,
The warning shows up in linux-next, the earliest commit we can bisect to is
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit a9730fca9946f3697410479e0ef1bd759ba00a77
Author: Christoph Lameter <cl@...ux.com>
AuthorDate: Mon Jun 29 09:28:08 2015 -0500
Commit: Linus Torvalds <torvalds@...ux-foundation.org>
CommitDate: Mon Jun 29 10:49:51 2015 -0700
Fix kmalloc slab creation sequence
This patch restores the slab creation sequence that was broken by commit
4066c33d0308f8 and also reverts the portions that introduced the
KMALLOC_LOOP_XXX macros. Those can never really work since the slab creation
is much more complex than just going from a minimum to a maximum number.
The latest upstream kernel boots cleanly on my machine with a 64 bit x86
configuration under KVM using either SLAB or SLUB.
Fixes: 4066c33d0308f8 ("support the slub_debug boot option")
