[PATCH 5.10 076/112] mm: sysctl: fix missing numa_stat when !CONFIG_HUGETLB_PAGE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Muchun Song <songmuchun@xxxxxxxxxxxxx>

[ Upstream commit 43b5240ca6b33108998810593248186b1e3ae34a ]

"numa_stat" should not be included in the scope of CONFIG_HUGETLB_PAGE, if
CONFIG_HUGETLB_PAGE is not configured even if CONFIG_NUMA is configured,
"numa_stat" is missed form /proc. Move it out of CONFIG_HUGETLB_PAGE to
fix it.

Fixes: 4518085e127d ("mm, sysctl: make NUMA stats configurable")
