I'm curious, in static void rcu_read_unlock_special(struct task_struct *t), on line 5 unsigned long flags is declared but uninitialized. Later, on line 11, it is passed-by-value to another function. Is there some missing code not shown that initializes flags?
Thank you for the neat article—I openly admit that a lot of it is hard for me to follow, but then I'm not as fluent in low-level kernel internals as Paul is. (And, I'm incredibly happy to know that people as knowledgeable as Paul are running the Linux Kernel Show™. ;-)
