------------------------------------------------------ From: Marc Herbert Marc.Herbert@linux.intel.com Subject: mm/hugetlb: move hugetlb_sysctl_init() to the __init section Date: Wed, 19 Mar 2025 06:00:30 +0000

hugetlb_sysctl_init() is only invoked once by an __init function and is merely a wrapper around another __init function so there is not reason to keep it.

Fixes the following warning when toning down some GCC inline options:

WARNING: modpost: vmlinux: section mismatch in reference: hugetlb_sysctl_init+0x1b (section: .text) -> __register_sysctl_init (section: .init.text)
