MEMBLOCK_RSRV_HUGETLB has no corresponding name, and regions with multiple flags only show the lowest set bit. Add the missing HugeTLB flag name and make memblock_debug_show() print all flags. With the series applied, a HugeTLB bootmem reservation is reported as: RSV_KERN|RSV_HUGETLB Meijing Zhao (2): mm: memblock: add missing HugeTLB flag name mm: memblock: show all region flags in debugfs mm/memblock.c | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) -- 2.25.1
