preempt_disable() is a no-op when !CONFIG_PREEMPT_COUNT, right?
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,

[lkp-robot] [brd] 316ba5736c: aim7.jobs-per-min -11.2% regression
by kernel test robot
Greeting,
FYI, we noticed a -11.2% regression of aim7.jobs-per-min due to commit:
commit: 316ba5736c9caa5dbcd84085989862d2df57431d ("brd: Mark as non-rotational")
https://git.kernel.org/cgit/linux/kernel/git/axboe/linux-block.git for-4.18/block
in testcase: aim7
on test machine: 40 threads Intel(R) Xeon(R) CPU E5-2690 v2 @ 3.00GHz with 384G memory
with following parameters:
disk: 1BRD_48G
fs: btrfs
test: disk_rw
load: 1500
cpufreq_governor: performance
test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.
test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/
Details are as below:

[lkp-robot] [mm] 9092c71bb7: blogbench.write_score -12.3% regression
by kernel test robot
Greeting,
FYI, we noticed a -12.3% regression of blogbench.write_score and a +9.6% improvement
of blogbench.read_score due to commit:
commit: 9092c71bb724dba2ecba849eae69e5c9d39bd3d2 ("mm: use sc->priority for slab shrink targets")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: blogbench
on test machine: 16 threads Intel(R) Xeon(R) CPU D-1541 @ 2.10GHz with 8G memory
with following parameters:
disk: 1SSD
fs: btrfs
cpufreq_governor: performance
test-description: Blogbench is a portable filesystem benchmark that tries to reproduce the load of a real-world busy file server.
test-url: https://www.pureftpd.org/project/blogbench
Details are as below:

[lkp-robot] [MD] 5a409b4f56: aim7.jobs-per-min -27.5% regression
by kernel test robot
Greeting,
FYI, we noticed a -27.5% regression of aim7.jobs-per-min due to commit:
commit: 5a409b4f56d50b212334f338cb8465d65550cd85 ("MD: fix lock contention for flush bios")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: aim7
on test machine: 40 threads Intel(R) Xeon(R) CPU E5-2690 v2 @ 3.00GHz with 384G memory
with following parameters:
disk: 4BRD_12G
md: RAID1
fs: xfs
test: sync_disk_rw
load: 600
cpufreq_governor: performance
test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.
test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/
Details are as below:

[lkp-robot] [shmem] a067b3644b: vm-scalability.throughput -73.2% regression
by kernel test robot
Greeting,
FYI, we noticed a -73.2% regression of vm-scalability.throughput due to commit:
commit: a067b3644bc70f2f715227bc3d22f5bc4a951dff ("shmem: Convert shmem_add_to_page_cache to XArray")
git://git.infradead.org/users/willy/linux-dax.git xarray
in testcase: vm-scalability
on test machine: qemu-system-x86_64 -enable-kvm -cpu qemu64,+ssse3 -smp 4 -m 4G
with following parameters:
runtime: 300s
size: 2T
test: shm-pread-seq
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp qemu -k <bzImage> job-script # job-script is attached in this email

398ceb91b8 ("RFC: debugobjects: capture stack traces at .."): BUG: kernel hang in boot stage
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is

commit 398ceb91b81505e7138eecdac870a59e85661671
Author: Daniel Vetter <daniel.vetter(a)ffwll.ch>
AuthorDate: Tue Mar 20 17:02:58 2018 +0100

RFC: debugobjects: capture stack traces at _init() time
Sometimes it's really easy to know which object has gone boom and
where the offending code is, and sometimes it's really hard. One case
we're trying to hunt down is when module unload catches a live debug
object, with a module with lots of them.
Capture a full stack trace from debug_object_init() and dump it when
there's a problem.
FIXME: Should we have a separate Kconfig knob for the backtraces,
they're quite expensive? Atm I'm just selecting it for the general
debug object stuff.
v2: Drop the locks for gathering&storing the backtrace. This is
required because depot_save_stack can call free_pages (to drop it's
preallocation), which can call debug_check_no_obj_freed, which will
recurse into the db->lock spinlocks.
