Hello, This patch set is to follow up modifications of struct page for makedumpfile which filters dump file. It's necessary to filter unnecessary compound pages in newer kernel as usual. Incidentally, [PATCH 1/2] was post in: https://lkml.org/lkml/2016/1/27/92 but it didn't get any response, I repost it here. Atsushi Kumagai (2): kexec: update VMCOREINFO for compound_order/dtor kexec: export OFFSET(page.compound_head) to check anonymous page kernel/kexec_core.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) Thanks, Atsushi Kumagai
