rcu: Abstract extended quiescent state determination
This commit is the fourth step towards full abstraction of all accesses to the ->dynticks counter, implementing previously open-coded checks and comparisons in new rcu_dynticks_in_eqs() and rcu_dynticks_in_eqs_since() functions. This abstraction will ease changes to the ->dynticks counter operation. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org>
