| |
Hi Paul,
After merging the rcu tree, today's linux-next build (x86_64 allmodconfig) failed like this:
kernel/rcu/rcutorture.c: In function 'rcu_torture_stats_print': kernel/rcu/rcutorture.c:1369:3: error: implicit declaration of function 'srcutorture_get_gp_data' [-Werror=implicit-function-declaration] srcutorture_get_gp_data(cur_ops->ttype, srcu_ctlp, ^
Caused by commit
b4d55cac0a93 ("srcu: Make rcutorture writer stalls print SRCU GP state")
This config has CONFIG_CLASSIC_SRCU=y and CONFIG_RCU_TORTURE_TEST=m, so CONFIG_RCU_TORTURE_TEST is not defined - CONFIG_RCU_TORTURE_TEST_MODULE is defined. You probably want to protect srcutorture_get_gp_data() with IS_ENABLED(CONFIG_RCU_TORTURE_TEST) instead.
I have used the rcu tree from next-20170418 for today.
-- Cheers, Stephen Rothwell
