Subject: mm: thp: fix build warning when CONFIG_SYSFS is disabled
Date: Mon, 11 Dec 2023 12:53:20 +0000
huge_anon_orders_lock is used only to serialize sysfs writers. So move
its definition so that it is within the CONFIG_SYSFS ifdefery to suppress
"defined but not used" warning when sysfs is disabled.
