• aed4e0468   rcu: Remove unused RCU list functions ... Browse Code »

  Given changes to callback migration, rcu_cblist_head(),
  rcu_cblist_tail(), rcu_cblist_count_cbs(), rcu_segcblist_segempty(),
  rcu_segcblist_dequeued_lazy(), and rcu_segcblist_new_cbs() are
  no longer used. This commit therefore removes them.

• f2dbe4a56   rcu: Localize rcu_state ->orphan_pend and ->orphan_done ... Browse Code »

  Given that the rcu_state structure's >orphan_pend and ->orphan_done
  fields are used only during migration of callbacks from the recently
  offlined CPU to a surviving CPU, if rcu_send_cbs_to_orphanage() and
  rcu_adopt_orphan_cbs() are combined, these fields can become local
  variables in the combined function. This commit therefore combines
  rcu_send_cbs_to_orphanage() and rcu_adopt_orphan_cbs() into a new
  rcu_segcblist_merge() function and removes the ->orphan_pend and
  ->orphan_done fields.

• 98059b986   rcu: Separately compile large rcu_segcblist functions ... Browse Code »

  This commit creates a new kernel/rcu/rcu_segcblist.c file that
  contains non-trivial segcblist functions. Trivial functions
  remain as static inline functions in kernel/rcu/rcu_segcblist.h
