| * | srcu: Make rcutorture writer stalls print SRCU GP state | Paul E. McKenney | 2017-04-26 | 1 | -0/+14 |
| | | | | | | | | | | | | In the past, SRCU was simple enough that there was little point in making the rcutorture writer stall messages print the SRCU grace-period number state. With the advent of Tree SRCU, this has changed. This commit therefore makes Classic, Tiny, and Tree SRCU report this state to rcutorture as needed. Signed-off-by: Paul E.

| * | srcu: Introduce CLASSIC_SRCU Kconfig option | Paul E. McKenney | 2017-04-18 | 1 | -0/+101 |
| The TREE_SRCU rewrite is large and a bit on the non-simple side, so this commit helps reduce risk by allowing the old v4.11 SRCU algorithm to be selected using a new CLASSIC_SRCU Kconfig option that depends on RCU_EXPERT. The default is to use the new TREE_SRCU and TINY_SRCU algorithms, in order to help get these the testing that they need. However, if your users do not require the update-side scalability that is to be provided by TREE_SRCU, select RCU_EXPERT and then CLASSIC_SRCU to revert back to the old classic SRCU algorithm.
