Subject: pid.h: include atomic.h
From: Grygorii Strashko <Grygorii.Strashko@linaro.org>
Date: Tue Jul 21 19:43:56 2015 +0300
From: Grygorii Strashko <Grygorii.Strashko@linaro.org>
This patch fixes build error:
CC kernel/pid_namespace.o
In file included from kernel/pid_namespace.c:11:0:
include/linux/pid.h: In function 'get_pid':
include/linux/pid.h:78:3: error: implicit declaration of function 'atomic_inc' [-Werror=implicit-function-declaration]
atomic_inc(&pid->count);
^
which happens when
CONFIG_PROVE_LOCKING=n
CONFIG_DEBUG_SPINLOCK=n
CONFIG_DEBUG_MUTEXES=n
CONFIG_DEBUG_LOCK_ALLOC=n
CONFIG_PID_NS=y
Vanilla gets this via spinlock.h.
