Hi all, After merging the rcu tree, today's linux-next build (x86_64 allmodconfig) failed like this:
ERROR: modpost: "rcu_read_lock_longwait_held" [kernel/rcu/rcutorture.ko]
undefined!
ERROR: modpost: "rcu_read_unlock_longwait" [kernel/rcu/rcutorture.ko] undefined!
ERROR: modpost: "rcu_read_lock_longwait" [kernel/rcu/rcutorture.ko] undefined!
Caused by commit
bd6ae31d1b1f ("rcutorture: Add the ability to torture RCU longsleep")
CONFIG_LONGWAIT_RCU=y
CONFIG_RCU_TORTURE_TEST=m
I have used the rcu tree from next-20210316 for today.
