The build errored on W=1 build (-Werror=missing-prototypes): CC arch/powerpc/mm/book3s64/pgtable.o CC arch/powerpc/kernel/process.o arch/powerpc/mm/book3s64/pgtable.c:478:5: error: no previous prototype for 'pmd_move_must_withdraw' [-Werror=missing-prototypes] 478 | int pmd_move_must_withdraw(struct spinlock *new_pmd_ptl, | ^~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors The errored line is introduced by commit 579b9239c1f386 ("powerpc/radix: Fix kernel crash with mremap()") Looking at the commit, it seems like GCC didn't see the prototype which had already been given, or am I missing something? Thanks. -- An old man doll... just what I always wanted! - Clara
