From 2e126aa29007353f069c3bab5c2cf52d231cd3ae Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Sat, 21 Jan 2023 12:11:51 +0200 Subject: [PATCH] mm/sparse: fix "unused function 'pgdat_to_phys'" warning W=1 build with clangs complains: mm/sparse.c:347:27: warning: unused function 'pgdat_to_phys' [-Wunused-function] static inline phys_addr_t pgdat_to_phys(struct pglist_data *pgdat) ^ 1 warning generated. pgdat_to_phys() is only used by functions defined when CONFIG_MEMORY_HOTREMOVE=y. Move pgdat_to_phys() under #ifdef CONFIG_MEMORY_HOTREMOVE to make clang happy.
