| kernel/rcutorture.c:492: error: ‘synchronize_rcu_bh’ undeclared here (not in a function) |
| |
| synchronize_rcu_bh() is not just called as a normal function, but can |
| also be referenced as a function pointer. When CONFIG_PREEMPT_RT_FULL |
| is enabled, synchronize_rcu_bh() is defined as synchronize_rcu(), but |
| needs to be defined without the parenthesis because the compiler will |
| complain when synchronize_rcu_bh is referenced as a function pointer |
| and not a function. |
