[PATCH rcu 03/12] rcutorture: Stop testing RCU Tasks Rude asynchronous APIs

From: neeraj . upadhyay
Date: Fri Aug 16 2024 - 02:51:24 EST


From: "Paul E. McKenney" <paulmck@xxxxxxxxxx>

The call_rcu_tasks_rude() and rcu_barrier_tasks_rude() APIs are currently
unused. Furthermore, the idea is to get rid of RCU Tasks Rude entirely
once all architectures have their deep-idle and entry/exit code correctly
marked as inline or noinstr. As a first step towards this goal, this
commit therefore removes these two functions from rcutorture testing.
