From cddba0af0b7919e93134469f6fdf29a7d362768a Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Fri, 24 Nov 2023 10:19:02 -0500 Subject: fs/Kconfig: make hugetlbfs a menuconfig Hugetlb vmemmap default option (HUGETLB_PAGE_OPTIMIZE_VMEMMAP_DEFAULT_ON) is a sub-option to hugetlbfs, but it shows in the same level as hugetlbfs itself, under "Pesudo filesystems". Make the vmemmap option a sub-option to hugetlbfs, by changing hugetlbfs into a menuconfig. When moving it, fix a typo 'v' spot by Randy.
