    Hi!

    > This is due to the commit 9f1eb38e0e11 ("mm, kmemleak: little

    > of pfn_valid(). However, in the CONFIG_MEMORY_HOTPLUG=y case,
    > pfn_to_online_page() does not call memblock_is_map_memory() while
    > pfn_valid() does.

    Commit 9f1eb38e0e11 does not seem to be in v4.19-stable tree. Is this
    commit still neccessary/good idea?

    Best regards,
    Pavel
