Hi all,
After merging the rcu tree, today's linux-next build (x86_64 allmodconfig)
failed like this:
arch/x86/xen/smp_pv.c: In function 'xen_pv_play_dead':
arch/x86/xen/smp_pv.c:439:2: error: implicit declaration of function 'tick_nohz_idle_stop_tick_protected'; did you mean 'tick_nohz_idle_stop_tick'? [-Werror=implicit-function-declaration]
tick_nohz_idle_stop_tick_protected();
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
tick_nohz_idle_stop_tick
Caused by commit
a96f9dca9820 ("idle: Prevent late-arriving interrupts from disrupting offline")
Also:
In file included from <command-line>:

include/linux/rcu_segcblist.h:75:2: error: unknown type name 'u8'

Caused by commits:
e084617762b7 ("rcu/nocb: Use separate flag to indicate disabled ->cblist")
5e114ba3d7a5 ("rcu/nocb: Use separate flag to indicate offloaded ->cblist")
9f3ca0945104 ("rcu/nocb: Atomic ->len field in rcu_segcblist structure")
We prefer our include files to be standalone now if at all possible.
I have used the rcu tree from next-20190809 for today.
