Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is

commit 19dfee4ca59f0c4ada2c5f1537949aaefeb4e6cc

net/packet: fix race condition between fanout_add and __unregister_prot_hook
If fanout_add is preempted after running po-> fanout = match
and before running __fanout_link,
it will cause BUG_ON when __unregister_prot_hook call __fanout_unlink
so, we need add mutex_lock(&fanout_mutex) to __unregister_prot_hook
or add spin_lock(&po->bind_lock) before po-> fanout = match
test on linux 4.1.12:
./trinity -c setsockopt -C 2 -X &
BUG: failure at net/packet/af_packet.c:1414/__fanout_unlink()!
Kernel panic - not syncing: BUG!

[lkp-robot] [EXPERIMENTAL] d1de9d10db: will-it-scale.per_process_ops -2.4% regression
by kernel test robot
Greeting,
FYI, we noticed a -2.4% regression of will-it-scale.per_process_ops due to commit:
commit: d1de9d10dbdac46e9f45325252464eaf2a386388 ("EXPERIMENTAL: Diagnostics for lost timer events")

054d249b0b ("x86/asm/64: Pass sp0 directly to load_sp0()"): BUG: sleeping function called from invalid context at include/linux/freezer.h:56
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/luto/linux.git x86/entry_consolidation
commit 054d249b0b01cfa1de290c5cc554c4ba5fa242c1
Author: Andy Lutomirski <luto(a)kernel.org>
AuthorDate: Tue Aug 15 12:12:53 2017 -0700
Commit: Andy Lutomirski <luto(a)kernel.org>
CommitDate: Sun Sep 10 08:37:30 2017 -0700
x86/asm/64: Pass sp0 directly to load_sp0()
load_sp0() had an odd signature:
void load_sp0(struct tss_struct *tss, struct thread_struct *thread);
Simplify it to:
void load_sp0(unsigned long sp0);
Signed-off-by: Andy Lutomirski <luto(a)kernel.org>
f3a89a25e9 x86/asm/32: Pull MSR_IA32_SYSENTER_CS update code out of native_load_sp0()
054d249b0b x86/asm/64: Pass sp0 directly to load_sp0()
6f85a1ba22 x86/traps: Use a new on_thread_stack() helper to clean up an assertion
