There were several other commits from Jérôme inbetween. I don't immediately see where the conflict came from, but as my patch is basically a revert of Jérôme's, and it was working in v4.16.4, maybe it's best if you drop the backport of b28b08de436a for now, let him comment on whether we still need it.

Do you already have a fixup for this? Jérôme initially created 6b368cd4a44c ("mm/hmm: avoid bloating arch that do not make use of HMM") which is part of v4.16. He noticed a build error that he fixed up with commit b28b08de436a ("mm/hmm: fix header file if/else/endif maze") which you backported as 25df8b83e867 into linux-4.16.y after v4.16.4. After that originally landed in mainline, I found another build error that I fixed with commit 9d8a463a7016 ("mm/hmm: fix header file if/else/endif maze, again") This fixes the issue that Randy is reporting now, please add that into v4.16.5.

Do you already have a fixup for this? Jérôme initially created 6b368cd4a44c ("mm/hmm: avoid bloating arch that do not make use of HMM") which is part of v4.16. He noticed a build error that he fixed up with commit b28b08de436a ("mm/hmm: fix header file if/else/endif maze") which you backported as 25df8b83e867 into linux-4.16.y after v4.16.4. After that originally landed in mainline, I found another build error that I fixed with commit 9d8a463a7016 ("mm/hmm: fix header file if/else/endif maze, again") This fixes the issue that Randy is reporting now, please add that into v4.16.5.

That patch does not apply to the stable trees. I'm also confused by the lack of "real" git commit ids that are being referred to here, that commit refers to one that is not valid. > 2018-04-27 0:52 GMT+03:00 Randy Dunlap: > > > https://bugzilla.kernel.org/show_bug.cgi?id=199515 > > > > kernel/fork.o: In function `__mmdrop': > > /kernel/build_kernel/linux-4.16.4/kernel/fork.c:600: undefined reference > > to `hmm_mm_destroy' What .config is creating this?

stable 4.16.5 hmm build error
https://bugzilla.kernel.org/show_bug.cgi?id=199515 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
