Gang Li dcadcf1c30 mm, hugetlb: skip irrelevant nodes in show_free_areas() ... show_free_areas() allows to filter out node specific data which is irrelevant to the allocation request. But hugetlb_show_meminfo() still shows hugetlb on all nodes, which is redundant and unnecessary. Use show_mem_node_skip() to skip irrelevant nodes. And replace hugetlb_show_meminfo() with hugetlb_show_meminfo_node(nid). before-and-after sample output of OOM: before: ``` [ 214.362453] Node 1 active_anon:148kB inactive_anon:4050920kB active_file:112kB inactive_file:100kB [ 214.375429] Node 1 Normal free:45100kB boost:0kB min:45576kB low:56968kB high:68360kB reserved_hig [ 214.388334] lowmem_reserve[]: 0 0 0 0 0 [ 214.390251] Node 1 Normal: 423*4kB (UE) 320*8kB (UME) 187*16kB (UE) 117*32kB (UE) 57*64kB (UME) 20 [ 214.397626] Node 0 hugepages_total=0 hugepages_free=0 hugepages_surp=0 hugepages_size=2048kB [ 214.401518] Node 1 hugepages_total=0 hugepages_free=0 hugepages_surp=0 hugepages_size=2048kB ``` after: ``` [ 145.069705] Node 1 active_anon:128kB inactive_anon:4049412kB active_file:56kB inactive_file:84kB u [ 145.110319] Node 1 Normal free:45424kB boost:0kB min:45576kB low:56968kB high:68360kB reserved_hig [ 145.152315] lowmem_reserve[]: 0 0 0 0 0 [ 145.155244] Node 1 Normal: 470*4kB (UME) 373*8kB (UME) 247*16kB (UME) 168*32kB (UE) 86*64kB (UME) [ 145.164119] Node 1 hugepages_total=0 hugepages_free=0 hugepages_surp=0 hugepages_size=2048kB ``` Link: https://lkml.kernel.org/r/20220706034655.1834-1-ligang.bdlg@bytedance.com Signed-off-by: Gang Li <ligang.bdlg@bytedance.com> Reviewed-by: Mike Kravetz <mike.kravetz@oracle.com> Cc: Muchun Song <songmuchun@bytedance.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>		2022-07-17 17:14:47 -07:00
