This can happen when all folios to be pinned are never added to the LRU, for example when vm_ops->fault allocated pages using cma_alloc() and never added them to the LRU.

That means in case if memory attached numa nodes are interleaved, then gather_bootmem_prealloc_parallel() will fail to scan few of these nodes. Since memory attached numa nodes can be interleaved in any fashion, hence ensure that the current code checks for all numa node ids (.size = nr_node_ids). Let's still keep max_threads as N_MEMORY, so that it can distributes all nr_node_ids among the these many no. threads. e.g. qemu cmdline ======================== numa_cmd="-numa node,nodeid=1,memdev=mem1,cpus=2-3 -numa node,nodeid=0,cpus=0-1 -numa dist,src=0,dst=1,val=20" mem_cmd="-object memory-backend-ram,id=mem1,size=16G" w/o this patch for cmdline (default_hugepagesz=1GB hugepagesz=1GB hugepages=2): ========================== ~ # cat /proc/meminfo |grep -i huge AnonHugePages: 0 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 0 kB with this patch for cmdline (default_hugepagesz=1GB hugepagesz=1GB hugepages=2): =========================== ~ # cat /proc/meminfo |grep -i huge AnonHugePages: 0 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 2 HugePages_Free: 2 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 2097152 kB Link: https://lkml.kernel.org/r/f8d8dad3a5471d284f54185f65d575a6aaab692b.1736592534.git.ritesh.list@gmail.com Fixes: b78b27d02930 ("hugetlb: parallelize 1G hugetlb initialization") Signed-off-by: Ritesh Harjani (IBM) Reported-by: Pavithra Prakash Suggested-by: Muchun Song Tested-by: Sourabh Jain Reviewed-by: Luiz Capitulino Acked-by: David Rientjes Cc: Donet Tom Cc: Gang Li Cc: Daniel Jordan Cc: Signed-off-by: Andrew Morton --- mm/hugetlb.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/hugetlb.c b/mm/hugetlb.c index 3b25b69aa94f..65068671e460 100644 --- a/mm/hugetlb.c +++ b/mm/hugetlb.c @@ -3309,7 +3309,7 @@ static void __init gather_bootmem_prealloc(void) .thread_fn = gather_bootmem_prealloc_parallel, .fn_arg = NULL, .start = 0, - .size = num_node_state(N_MEMORY), + .size = nr_node_ids, .align = 1, .min_chunk = 1, .max_threads = num_node_state(N_MEMORY), -- 2.51.0 From e5eaa1bbe2813ac34788e485283be75f9d07137b Mon Sep 17 00:00:00 2001 From: Carlos Bilbao Date: Wed, 29 Jan 2025 19:22:44 -0600 Subject: [PATCH 05/16] mailmap, MAINTAINERS, docs: update Carlos's email address Update .mailmap to reflect my new (and final) primary email address, carlos.bilbao@kernel.org.
