Re: maybe dumb question about RCU

256 If you are going to be fetching multiple fields from the 257 RCU-protected structure, using the local variable is of 258 course preferred. Repeated rcu_dereference() calls look 259 ugly and incur unnecessary overhead on Alpha CPUs.

"look ugly and incur unnecessary overhead on Alpha CPUs" is a long way from "can return different pointer values", which is what it should say.

I agree, that statement is not only misleading, but incorrect too. Maybe we can delete it and update it with a "Note:" about your findings? How about sending a doc patch for it?
