Please add 4.17 commit 145e1a71e090575c74969e3daa8136d1e5b99fc8 ("mm: fix the NULL mapping case in __isolate_lru_page()") to the 4.16, 4.14, 4.9, 4.4, 3.18 and 3.2 stable kernel trees.
Two things happened after I'd sent it to Andrew without a stable tag:
- Ivan posted an equivalent patch: after painstaking bisection, he had found the fixed commit to be what was causing strange blocking (surprising to the rest of us, we had imagined it just suboptimal).
- The fixed commit arrived in five stable kernel releases (presumably arriving there by auto selection: which will in due course pick up this fix to it, but I don't know its cadence).
Thanks for letting us know, now queued up for 4.16, 4.14, 4.9, 4.4, and 3.18. 3.2 is now end-of-life, but 3.16 is still alive, Ben can take care of that.
thanks,
