Subject: [PATCH 0/2] Enable ARCH_WANT_HUGETLB_PAGE_OPTIMIZE_VMEMMAP & fixup race condition on PG_dcache_clean
Date: Sun, 23 Oct 2022 09:32:03 -0400	[thread overview]
Message-ID: <20221023133205.3493564-1-guoren@kernel.org> (raw)

From: Guo Ren <guoren@linux.alibaba.com>

The first patch fixup race condition on PG_dcache_clean which found in
arm64. Then enable ARCH_WANT_HUGETLB_PAGE_OPTIMIZE_VMEMMAP and tested
with simple hugetlbfs test case.

# cat /proc/sys/vm/hugetlb_optimize_vmemmap
1
# echo 8 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
# mount -t hugetlbfs none test/ -o pagesize=2048k
# ./myhugemap_test
# umount test/
# echo 0 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages

No problem found.
