Michal, as this is the memcg tree and not akpm or linux-next could this
build error be a merge problem in your tree?

Hmm, maybe my tree is missing some follow up fix but git diff sees
nothin relevant. Neverheless I have noticed that both CONFIG_SWAP and
CONFIG_NFS_SWAP are disabled. get_kernel_page is defined in mm/swap.c
but that one should be compiled in regardless the SWAP configuration.

I do not see this error on x86_64 with the above two disabled. Is it
possible that this is something m32r specific? Possibly some confusion
wrt. EXPORT_SYMBOL_GPL?

I find that at _that_ commit, get_kernel_page() is defined in
mm/memory.c which will only be compiled on CONFIG_MMU.

The get_kernel_page*() definitions are later moved to mm/swap.c by

I tried EXPORT_SYMBOL, still the same. So it should be due to related
to CONFIG_MMU which is missing in m32104ut_defconfig.

But that means that it is not CONFIG_MMU dependent anymore, right?

Yes. It presents a problem for bisectability, however it seems only a
problem in the since-3.5 branch: the patches sent to Linus are
actually in good order. So it should be fine.

Btw, is it meaningful for me to test the bisectability of all the
memcg branches? If not, you may give me a list or pattern for me to
take care.

Thanks,
Fengguang

OK, I see so this is a bisectability test and the tip of the branch
compiles without any issues, right?

Well, I do not think that this kind of test makes sense for the tree
because fixups are always done as a separate commits to prevent from
rebasing. Andrew always folds the fixups into the final patch which is
sent to Linus or who ever should push it further.

Yeah.

It have some other issues instead. You didn't receive emails about
them because my system only complaint about "new" issues :-)

Yeah the build script have taken care of these follow-up fixes:

has_akpm_fix()
{       
        [[ $branch = 'next/akpm' || $branch =~ 'memcg/' ]] || return 1

        [[ $(git_commit_changelog $next_commit) =~ (build|compile|gcc|sparse|error|warning) ]] && return 0
        return 1
}

I assume those are present in the mmotm as well.

OK, but I still think that the tree is not constructed to be bisectable.
It's main purpose is the provide a common code base for -mm tree which
is easier to work with than linux-next. The compilation coverage is
really great and thanks a lot for doing that but I think that
bisectability testing is not needed.

Thanks

I think so, too.

Understand. I'll test the HEAD commits only for the memcg branches.

OK.  I think it is sufficient to test only the last since-X.Y branch
(X.Y comes from the last major release).
Thanks a lot for doing those tests!
