This commit adds same_state_synchronize_rcu() and same_state_synchronize_rcu_full() functions to compare grace-period state values, for example, those obtained from get_state_synchronize_rcu() and get_state_synchronize_rcu_full(). These functions allow small structures to omit these state values by placing them in list headers for lists containing structures with the same token value. Presumably the per-structure list pointers are the same ones used to link the structures into whatever reader-accessible data structure was used. This commit also adds both NUM_ACTIVE_RCU_POLL_OLDSTATE and NUM_ACTIVE_RCU_POLL_FULL_OLDSTATE, which define the maximum number of distinct unsigned long values and rcu_gp_oldstate values, respectively, corresponding to not-yet-completed grace periods. These values can be used to size arrays of the list headers described above. Signed-off-by: Paul E. McKenney <paulmck@kernel.org> |
