Paul E. McKenney 6a4fea54ab rcu: Use READ_ONCE() for ->expmask in rcu_read_unlock_special() ... commit c51f83c315c392d9776c33eb16a2fe1349d65c7f upstream. The rcu_node structure's ->expmask field is updated only when holding the ->lock, but is also accessed locklessly. This means that all ->expmask updates must use WRITE_ONCE() and all reads carried out without holding ->lock must use READ_ONCE(). This commit therefore changes the lockless ->expmask read in rcu_read_unlock_special() to use READ_ONCE(). Reported-by: syzbot+99f4ddade3c22ab0cf23@syzkaller.appspotmail.com Signed-off-by: Paul E.
