It is therefore time to\nenlist the aid of lockdep.\n\nThis set of patches is inspired by earlier work by Peter\nZijlstra and Thomas Gleixner, and takes the following approach:\n\no\tSet up separate lockdep classes for RCU, RCU-bh, and RCU-sched.\n\no\tSet up separate lockdep classes for each instance of SRCU.\n\no\tCreate primitives that check for being in an RCU read-side\n\tcritical section. These return exact answers if lockdep is\n\tfully enabled, but if unsure, report being in an RCU read-side\n\tcritical section. (We want to avoid false positives!)\n\tThe primitives are:\n\n\tFor RCU: rcu_read_lock_held(void)\n\n\tFor RCU-bh: rcu_read_lock_bh_held(void)\n\n\tFor RCU-sched: rcu_read_lock_sched_held(void)\n\n\tFor SRCU: srcu_read_lock_held(struct srcu_struct *sp)\n\no\tAdd rcu_dereference_check(), which takes a second argument\n\tin which one places a boolean expression based on the above\n\tprimitives and/or lockdep_is_held().\n\no\tA new kernel configuration parameter, CONFIG_PROVE_RCU, enables\n\trcu_dereference_check().

This means the call to\npercpu_counter_add will always add to the global count which is\nprotected by a spinlock and we end up with a global spinlock in\nthe scheduler.\n\nBased on an idea by KOSAKI Motohiro, this patch scales the batch\nvalue by cputime_one_jiffy such that we have the same batch\nlimit as we would if CONFIG_VIRT_CPU_ACCOUNTING was disabled.\nHis patch did this once at boot but that initialisation happened\ntoo early on PowerPC (before time_init) and it was never updated\nat runtime as a result of a hotplug cpu add/remove.\n\nThis patch instead scales percpu_counter_batch by\ncputime_one_jiffy at runtime, which keeps the batch correct even\nafter cpu hotplug operations. We cap it at INT_MAX in case of\noverflow.\n\nFor architectures that do not support\nCONFIG_VIRT_CPU_ACCOUNTING, cputime_one_jiffy is the constant 1\nand gcc is smart enough to optimise min(s32\npercpu_counter_batch, INT_MAX) to just percpu_counter_batch at\nleast on x86 and PowerPC.
