kernel/fork.o: In function `__mmdrop': /kernel/build_kernel/linux-4.16.4/kernel/fork.c:600: undefined reference to `hmm_mm_destroy' "It is also reproduced in linux-4.16.5" There have been a few attempts to fix this build error. The kernel mainline repo seems to have it fixed, but it looks to me like Arnd's latest patch (9d8a463a7016e: "mm/hmm: fix header file if/else/endif maze, again") was mis-merged to 4.16.5 stable. Please take a look. Do you already have a fixup for this? thanks, -- ~Randy
