Hi,

kernel BUG at mm/huge_memory.c:2736(linux 5.10.29) is triggered
by some files write test.

mm/huge_memory.c:
        if (IS_ENABLED(CONFIG_DEBUG_VM) && mapcount) {
            pr_alert("total_mapcount: %u, page_count(): %u\n",
                    mapcount, count);
            if (PageTail(page))
                dump_page(head, NULL);
            dump_page(page, "total_mapcount(head) > 0");
L2736:           BUG();
        }

kernel version:5.10.29

We just can tell the mapcount of the page is not zero from the current
log, it might mean the unmap_page() call is failed. It seems you have
CONFIG_DEBUG_VM enabled, could you please paste more log? There is
"VM_BUG_ON_PAGE(!unmap_success, page)" in unmap_page(). It should be
able to tell us if unmap_page() is failed or not, or something else
happened.

The kernel config:

Hi,

This problem yet not happen when switched from 
CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y
to
CONFIG_TRANSPARENT_HUGEPAGE_MADVISE=y

so it seems a CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS related problem.

_MADVISE means THP is not going to be used unless MADV_HUGEPAGE is
called for some address areas. _ALWAYS means THP should be used
whenever possible. So if your applications don't call
madvise(MADV_HUGEPAGE) there should be no THP at all.

And you could adjust the setting by manipulating
/sys/kernel/mm/transparent_hugepage/enabled rather than
reconfigure/rebuild the kernel.

Added Kirill in this loop too, he may have some insights.

Thanks a lot for pasting the full log. It seems the BUG_ON in
unmap_page() and VM_BUG_ON_PAGE(compound_mapcount(head), head) were
not triggered. But the dumped page shows its total_mapcount is 511. It
means 511 subpages of the huge page are PTE mapped. It seems all tail
pages are PTE mapped. It may be because unmap_page() is failed or they
are mapped again after unmap_page().

But the VM_BUG_ON_PAGE just checks compound_mapcount, and it seems
page_mapcount() call in unmap_page() also just checks
compound_mapcount and the mapcount of the head page. If the mapcount
of the head page is 0 and compound_mapcount is also 0, try_to_unmap()
considers unmap is successful.

So we can't tell which case it is although I don't think of how
unmap_page() could fail for this case.  I think we should check the
total mapcount in try_to_unmap() instead.

Can you please try the below debug patch (untested) to help narrow
down the problem?

With this patch, the problem yet not happen after 4 tests(5.10.x).

By the way, the problem does not happen in 5.4.x.(>about 120 tests)
does this match the code version?

Hi,

> With this patch, the problem yet not happen after 4 tests(5.10.x).

With this patch , another problem happened at 6th test.

kernel BUG at mm/huge_memory.c:2343!
static void unmap_page(struct page *page)
{
    enum ttu_flags ttu_flags = TTU_IGNORE_MLOCK |
        TTU_RMAP_LOCKED | TTU_SPLIT_HUGE_PMD;
    bool unmap_success;

    VM_BUG_ON_PAGE(!PageHead(page), page);

    if (PageAnon(page))
        ttu_flags |= TTU_SPLIT_FREEZE;

    unmap_success = try_to_unmap(page, ttu_flags);
L2343:VM_BUG_ON_PAGE(!unmap_success,page);
}


This is the full dmesg output.

Thanks for running the test. This is what I expected from the debug
patch. It means try_to_unmap() didn't unmap the huge page
successfully. The huge page is PTE-mapped, try_to_unmap() is supposed
to unmap every mapped subpage. But it seems it didn't unmap any
subpage at all (the refcount of the huge page is 512 per the log from
earlier email).

By reading the code, I didn't figure out what went wrong yet. You
mentioned that the 5.4.x kernel is fine, so may you try to do some
bisect?

This maybe happen on some memory reclaim path.

Our application need to process the file about 300G-400G.

We have 4 servers, two servers have 192G memory, 1 server has 512G
memory, 1 server has 768G memory.

If the memory(total memory * 10 / 12 - 120G) is enough to process the
files, no temp file is needed. else, we will write the buffer to temp
file, and continue to process another part.

this problem happened on the server with 192G memory && kernel 5.10.x,
but yet not happen on the server with kernel 5.4.x  ||
total memory>=512G.

so this maybe a timing problem too. debug code maybe userful than code bisect?

fedora with new linux kernel configured with CONFIG_TRANSPARENT_HUGEPAGE_MADVISE=y,
so new linux kernel with CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y maybe not well
tested?

Yes, it does. The stack trace already showed so.

If you want to add some debug code, there would be a lot of places to add.

I'd suggest you try to add some debug code in page_vma_mapped_walk()
first, particularly in check_pte(). I suspect it didn't find valid
PTEs since the unmap itself would be quite simple. (I assumed
CONFIG_MIGRATION is enabled).

Then you can try to add debug code in try_to_unmap_one().

And I'm not sure if khugepaged may have race condition with split, it
sounds unlikely, but collapsing PTE-mapped THP support was added in
v5.8, so you may try to reproduce this on v5.7 to narrow it down.

This is the test result on linux 5.7.17/5.8.18/5.9.16 with
CONFIG_DEBUG_VM=y and
CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y,
but without the debug patch from Yang Shi 

linux 5.7.17: this problem yet not happan after 6 tests.

linux 5.8.18: this problem yet not happan after 6 tests.

linux 5.19.16: this problem yet not happen ater 5 tests,
	but triggered a new problem, see dmesg-5.9.16.txt

we also noticed that the btrfs filesystem performance improvement in
5.10.x, that maybe change the memory reclaim frequency too.
