Hi Dave, With Ubuntu and Debian having backported this into their kernels, we're finally seeing testing from places we hadn't seen prior, which is nice. With that comes more fixes: 1) The CI for PPC64 was running with extremely small stacks for 64-bit, causing spurious crashes in surprising places. 2) There's was an old leftover routing loop restriction, which no longer makes sense given the queueing architecture, and was causing problems for people who really did want nested routing. 3) Not yielding our kthread on CONFIG_PREEMPT_VOLUNTARY systems caused RCU stalls and other issues, reported by Wang Jian, with the fix suggested by Sultan Alsawaf. 4) Clang spewed warnings in a selftest for CONFIG_IPV6=n, reported by Arnd Bergmann. 5) A complicated if statement was simplified to an assignment while also making the likely/unlikely hinting more correct and simple, and increasing readability, suggested by Sultan. Patches (2) and (3) have Fixes: lines and are probably good candidates for stable. Thanks, Jason Jason A.
