Yes, that commit helps where I don't have to do any fixes. Greg, Can you please backport the following commits to 5.10, and then reapply this patch? 29d2bb94a8a1 ("srcu: Provide internal interface to start a Tree SRCU grace period") 5358c9fa54b0 ("srcu: Provide polling interfaces for Tree SRCU grace periods") 1a893c711a60 ("srcu: Provide internal interface to start a Tiny SRCU grace period") 74612a07b83f ("srcu: Make Tiny SRCU use multi-bit grace-period counter") 8b5bd67cf642 ("srcu: Provide polling interfaces for Tiny SRCU grace periods") Thanks, -- Steve
