This commit removes rcu_sched_get_gp_seq(), rcu_bh_get_gp_seq(), rcu_exp_batches_completed_sched(), rcu_sched_force_quiescent_state(), and rcu_bh_force_quiescent_state(), which are no longer used because rcutorture no longer does "rcu_bh" and "rcu_sched" torture types. Signed-off-by:

Now that the RCU-bh and RCU-sched update-side functions are simple wrappers around their RCU counterparts, there isn't a whole lot of point in testing them. This commit therefore removes the "rcu_bh" and "sched" torture types from rcuperf. Signed-off-by:

Now that the RCU-bh and RCU-sched update-side functions are simple wrappers around their RCU counterparts, there isn't a whole lot of point in testing them. This commit therefore removes the self-test capability and removes the corresponding kernel-boot parameters. It also updates the various rcutorture .boot files to remove the kernel boot parameters that call for testing RCU-bh and RCU-sched. Signed-off-by:

Since there is now a single consolidated RCU flavor, rcutorture needs to test extending of RCU readers via rcu_read_lock_bh() and rcu_read_lock_sched(). This commit adds this support, with added checks (just like for local_bh_enable()) to ensure that rcu_read_unlock_bh() will not be invoked while interrupts are disabled. Signed-off-by:

This commit saves a few lines by consolidating the RCU-sched function definitions at the end of include/linux/rcupdate.h. This consolidation also makes it easier to remove them all when the time comes. Signed-off-by:

The rcu_gp_kthread() function is long and deeply indented, so this commit pulls the loop that repeatedly invokes rcu_gp_fqs() into a new rcu_gp_fqs_loop() function. Signed-off-by:

Consolidation of the RCU flavors into one makes increment_cpu_stall_ticks() a trivial one-line function with only one caller. This commit therefore inlines it. Signed-off-by:

Now that there is only one rcu_state structure, there is less point in maintaining a pointer to it. This commit therefore replaces rsp with &rcu_state in rcu_cpu_starting() and rcu_init_one(). Signed-off-by:

Now that there is only ever a single flavor of RCU in a given kernel build, there isn't a whole lot of point in having a flavor-traversal macro. This commit therefore removes it and converts calls to it to straightline code, inlining trivial functions as appropriate. Signed-off-by:

This commit removes the last non-flavor-traversal rsp local variable from kernel/rcu/tree_plugin.h in favor of &rcu_state. The flavor-traversal locals will be removed with the removal of flavor traversal. Signed-off-by:

Now that there is only one rcu_state structure, there is no need for the rcu_data structure to indicate which it corresponds to. This commit therefore removes the rcu_data structure's ->rsp field, replacing all remaining uses of it with &rcu_state. Signed-off-by:

There now is only one rcu_state structure in a given build of the Linux kernel, so there is no need to pass it as a parameter to RCU's rcu_node tree's accessor macros. This commit therefore removes the rsp parameter from those macros in kernel/rcu/rcu.h, and removes some now-unused rsp local variables while in the area. Signed-off-by:

This commit therefore removes the rsp parameter from rcu_boot_init_percpu_data(), rcu_init_percpu_data(), rcu_cleanup_dying_idle_cpu(), and rcu_migrate_callbacks(). While in the neighborhood, line the last three into rcutree_prepare_cpu(), rcu_report_dead() and rcutree_migrate_callbacks(), respectively. This also gets rid of the for_each_rcu_flavor() calls that were in those tree functions. Signed-off-by:
