In kernels built with CONFIG_PREEMPT_RT=n, spinlock critical sections are RCU readers because they disable preemption. However, they are also RCU readers in CONFIG_PREEMPT_RT=y because in that case the locking primitives contain rcu_read_lock() and rcu_read_unlock(). Therefore, upgrade checklist.rst to document this non-obvious case. While in the area, fix a typo by changing "read-side critical" to "read-side critical section". Signed-off-by: Paul E.
