Subject: [Suggestion] kernel/rcutorture.c: about using scnprintf() instead
 of sprintf().

Hello Maintainers:

In srcu_torture_stats(), if cpus are more than 1K, the PAGE_SIZE will
not be enough.

In rcu_torture_printk(), the 'page' maximized size is 4096, it has a
function pointer for printing, which not tell its maximized length.

Welcome any additional suggestions or completions.

Thanks.
