RCU has only one multi-tail callback list, which is implemented via the nxtlist, nxttail, nxtcompleted, qlen_lazy, and qlen fields in the rcu_data structure, and whose operations are open-code throughout the Tree RCU implementation. This has been more or less OK in the past, but upcoming callback-list optimizations in SRCU could really use a multi-tail callback list there as well. This commit therefore abstracts the multi-tail callback list handling into a new kernel/rcu/rcu_segcblist.h file, and uses this new API. The simple head-and-tail pointer callback list is also abstracted and applied everywhere except for the NOCB callback-offload lists. (Yes, the plan is to apply them there as well, but this commit is already bigger than would be good.) Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> |
