[PATCH RFC rcu 01/19] srcu: Add whitespace to __SRCU_STRUCT_INIT() & __DEFINE_SRCU()

From: Paul E. McKenney
Date: Thu Mar 23 2023 - 20:19:54 EST


This is a whitespace-only commit with no change in functionality.
Its purpose is to prepare for later commits that: (1) Cause statically
allocated srcu_struct structures to rely on compile-time initialization
and (2) Move fields from the srcu_struct structure to a new srcu_usage
structure.
