| |
Hello!
This commit does RCU-consolidation cleanups that get rid of pointers to the sole remaining rcu_state structure:
1-40: Remove the "rsp" parameter from numerous functions, given that the corresponding argument will always be &rcu_state.
41. Remove rcu_data structure's ->rsp field, now that it always contains a pointer to rcu_state.
42. Remove non-flavor-traversal rsp local variable from tree_plugin.h.
43. Remove the for_each_rcu_flavor() flavor-traversal macro, given that there is now only ever one flavor to traverse.
44. Simplify rcutorture_get_gp_data() based on there now being only one rcu_state structure.
45. Restructure rcu_check_gp_kthread_starvation() based on there now being only one rcu_state structure.
46. Restructure RCU CPU stall warnings based on there now being only one rcu_state structure.
47. Restructure grace-period management code based on there now being only one rcu_state structure.
48. Restructure callback registration/invocation code based on there now being only one rcu_state structure.
49. Restructure quiescent-state and grace-period-nonstart code based on there now being only one rcu_state structure.
50. Restructure rcu_barrier() based on there now being only one rcu_state structure.
51. Restructure initialization code based on there now being only one rcu_state structure.
52. Fix typo in force_qs_rnp()'s parameter's parameter, which was located by searching for "rsp".
Thanx, Paul
