Reverting the rcu swait patches fixed the boot problem. Then when I was
looking at the revert itself, this stood out like a sore thumb.
static void rcu_nocb_gp_cleanup(struct rcu_state *rsp, struct rcu_node *rnp) {
- swait_wake(&rnp->nocb_gp_wq[rnp->completed & 0x1]);
+ wake_up_all(&rnp->nocb_gp_wq[rnp->completed & 0x1]);
}
See the problem there?
