It seems like in v6.10 you hit a BUG in zswap (corruption?), and in v6.9 you hit a soft lockup with a zswap lock showing up in the splat. Not sure how they are relevant. Is the soft lockup reproducible in v6.10 as well? Since you have a narrow window (6.8.2 to 6.9) and a reproducer for the soft lockup problem, can you try bisecting? Thanks!
