H A Dsrcutree.cc69a00a1 Tue Jan 25 23:41:10 GMT 2022 Paul E. McKenney <[email protected]> srcu: Add boot-time control over srcu_node array allocation

This commit adds an srcu_tree.convert_to_big kernel parameter that either
refuses to convert at all (0), converts immediately at init_srcu_struct()
time (1), or lets rcutorture convert it (2). An addition contention-based
dynamic conversion choice will be added, along with documentation.
