Subject: [LKP] 02a5c550b2 BUG: kernel reboot-without-warning in test stage
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is

commit 02a5c550b2738f2bfea8e1e00aa75944d71c9e18

rcu: Abstract extended quiescent state determination
This commit is the fourth step towards full abstraction of all accesses
to the ->dynticks counter, implementing previously open-coded checks and
comparisons in new rcu_dynticks_in_eqs() and rcu_dynticks_in_eqs_since()
functions. This abstraction will ease changes to the ->dynticks counter
operation.
