[block] 6861428921: vm-scalability.median 1003.2% improvement
by kernel test robot
Greeting,
FYI, we noticed a 1003.2% improvement of vm-scalability.median due to commit:
commit: 6861428921b51113520cd47897be6c2774e4fc58 ("block: always define BIO_MAX_PAGES as 256")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: vm-scalability
on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory
with following parameters:
runtime: 300
thp_enabled: always
thp_defrag: always
nr_task: 32
nr_ssd: 1
test: swap-w-seq
cpufreq_governor: performance
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.

[lib] 50ceaa95ea: BUG:KASAN:stack-out-of-bounds_in_l
by kernel test robot
FYI, we noticed the following commit (built with gcc-5):
commit: 50ceaa95ea09703722b30b4afa617c972071cd7f ("lib: Introduce test_stackinit module")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: locktorture
with following parameters:
runtime: 300s
test: cpuhotplug
test-description: This torture test consists of creating a number of kernel threads which acquire the lock and hold it for specific amount of time, thus simulating different critical region behaviors.
test-url: https://www.kernel.org/doc/Documentation/locking/locktorture.txt
on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 2G

1a92702b56 ("slob: Respect list_head abstraction layer"): kernel BUG at lib/list_debug.c:28!
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://github.com/tcharding/linux slab-lru
commit 1a92702b56442beb103172415a9930e8d8ae9eea
Author: Tobin C. Harding <tobin(a)kernel.org>
AuthorDate: Thu Mar 14 10:38:59 2019 +1100
Commit: Tobin C. Harding <tobin(a)kernel.org>
CommitDate: Mon Mar 18 10:19:44 2019 +1100
slob: Respect list_head abstraction layer
Currently we reach inside the list_head. This is a violation of the
layer of abstraction provided by the list_head. It makes the code
fragile. More importantly it makes the code wicked hard to understand.
The code logic is based on the page in which an allocation was made, we
want to modify the slob_list we are working on to have this page at the
front. We already have a function to check if an entry is at the front
of the list. Recently a function was added to list.h to do the list
rotation. We can use these two functions to reduce line count, reduce
code fragility, and reduce cognitive load required to read the code.
Use list_head functions to interact with lists thereby maintaining the
abstraction provided by the list_head structure.
