Hi, This patchset tries to solve the issue among memory_hotplug, hugetlb and hwpoison. Based on the discussion on v1, this version goes in the direction of changing the behavior of memory hotplug for hwpoison: - hwpoison pages should not prevent memory hotremove, - memory block with hwpoison pages should not be onlined. I tested both with ACPI-based and sysfs-based memory hotplug, and passed basic testcases. Any comments and feedbacks would be appreciated. Thanks, Naoya Horiguchi v1: https://lore.kernel.org/linux-mm/20220427042841.678351-1-naoya.horiguchi@xxxxxxxxx/T --- Summary: Naoya Horiguchi (4): mm,hwpoison,hugetlb,memory_hotplug: hotremove memory section with hwpoisoned hugepage mm/hwpoison: move definitions of num_poisoned_pages_* to memory-failure.c mm/hwpoison: pass pfn to num_poisoned_pages_*() mm/hwpoison: introduce per-memory_block hwpoison counter arch/parisc/kernel/pdt.c | 5 ++--- drivers/base/memory.c | 36 ++++++++++++++++++++++++++++++++++++ include/linux/memory.h | 3 +++ include/linux/mm.h | 12 ++++++++++++ include/linux/swapops.h | 25 ------------------------- mm/internal.h | 8 -------- mm/memory-failure.c | 45 +++++++++++++++++++++++---------------------- mm/memory_hotplug.c | 22 +++++++++++----------- mm/sparse.c | 2 -- 9 files changed, 87 insertions(+), 71 deletions(-)
