by Philip Li
Hi all, this is Philip who maintains the 0-Day CI test service. Thanks for
subscribing to the service. It has been a long time we use both kbuild test
robot and kernel test robot to send out report. From now on, we want to
combine two mails to kernel test robot, which is a single voice for the
whole service. Sorry for any inconvenience caused by this change, which may
impact your mail setting.
Meanwhile, we have mail address lkp(a)intel.com for you to reach us. Kindly
drop us mail at kernel test robot <lkp(a)intel.com> or submit issue at
https://github.com/intel/lkp-tests for any question and support you need.

28307d938f ("percpu: make pcpu_alloc() aware of current gfp .."): BUG: kernel reboot-without-warning in boot stage
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 28307d938fb2e4056ed4c982c06d1503d7719813
Author: Filipe Manana <fdmanana(a)suse.com>
AuthorDate: Thu May 7 18:36:10 2020 -0700

CommitDate: Thu May 7 19:27:21 2020 -0700
percpu: make pcpu_alloc() aware of current gfp context
Since 5.7-rc1, on btrfs we have a percpu counter initialization for
which we always pass a GFP_KERNEL gfp_t argument (this happens since
commit 2992df73268f78 ("btrfs: Implement DREW lock")).
That is safe in some contextes but not on others where allowing fs
reclaim could lead to a deadlock because we are either holding some
btrfs lock needed for a transaction commit or holding a btrfs
transaction handle open. Because of that we surround the call to the
function that initializes the percpu counter with a NOFS context using
memalloc_nofs_save() (this is done at btrfs_init_fs_root()).
However it turns out that this is not enough to prevent a possible
deadlock because percpu_alloc() determines if it is in an atomic context
by looking exclusively at the gfp flags passed to it (GFP_KERNEL in this
case) and it is not aware that a NOFS context is set.
Because percpu_alloc() thinks it is in a non atomic context it locks the
pcpu_alloc_mutex. This can result in a btrfs deadlock when
pcpu_balance_workfn() is running, has acquired that mutex and is waiting
for reclaim, while the btrfs task that called percpu_counter_init() (and
therefore percpu_alloc()) is holding either the btrfs commit_root
semaphore or a transaction handle (done fs/btrfs/backref.c:
iterate_extent_inodes()), which prevents reclaim from finishing as an
attempt to commit the current btrfs transaction will deadlock.
Lockdep reports this issue with the following trace:

This could be fixed by making btrfs pass GFP_NOFS instead of GFP_KERNEL
to percpu_counter_init() in contextes where it is not reclaim safe,
however that type of approach is discouraged since
memalloc_[nofs|noio]_save() were introduced. Therefore this change
makes pcpu_alloc() look up into an existing nofs/noio context before
deciding whether it is in an atomic context or not.

lockdep: Prepare for NMI IRQ state tracking
There is no reason not to always, accurately, track IRQ state.
This change also makes IRQ state tracking ignore lockdep_off().

ac7c3e4ff4 ("compiler: enable CONFIG_OPTIMIZE_INLINING forcibly"): 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
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit ac7c3e4ff401b304489a031938dbeaab585bfe0a
Author: Masahiro Yamada <yamada.masahiro(a)socionext.com>
AuthorDate: Wed Sep 25 16:47:42 2019 -0700
Commit: Linus Torvalds <torvalds(a)linux-foundation.org>
CommitDate: Wed Sep 25 17:51:40 2019 -0700
compiler: enable CONFIG_OPTIMIZE_INLINING forcibly
Commit 9012d011660e ("compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING") allowed all architectures to enable this
option. A couple of build errors were reported by randconfig, but all of
them have been ironed out.
Towards the goal of removing CONFIG_OPTIMIZE_INLINING entirely (and it
will simplify the 'inline' macro in compiler_types.h), this commit changes
it to always-on option. Going forward, the compiler will always be
allowed to not inline functions marked 'inline'.
This is not a problem for x86 since it has been long used by
arch/x86/configs/{x86_64,i386}_defconfig.
I am keeping the config option just in case any problem crops up for other
architectures.
The code clean-up will be done after confirming this is solid.
