rcu/debug: Add wake-up debugging for lazy callbacks
This patch adds initial debugging for lazy callback: whether the
callback does a wake up or not. We see that callbacks doing wake ups are
usually associated with synchronous use cases (SCSI, rcu_sync,
synchronize_rcu() etc).
The code is not very intrusive as almost all the logic is in
'lazy-debug.h' with just a few calls from tree.c
In the future, we will add more functionality such as ensuring
callbacks execute in bounded time.
