documentation: Record rcu_dereference() value mishandling Recent LKML discussings (see http://lwn.net/Articles/586838/ and http://lwn.net/Articles/588300/ for the LWN writeups) brought out some ways of misusing the return value from rcu_dereference() that are not necessarily completely intuitive. This commit therefore documents what can and cannot safely be done with these values. Signed-off-by: Paul E. McKenney <[email protected]> Reviewed-by: Josh Triplett <[email protected]>
