If CONFIG_ELF_CORE is not set: fs/coredump.c:835:12: error: ‘dump_emit_page’ defined but not used [-Werror=unused-function] 835 | static int dump_emit_page(struct coredump_params *cprm, struct page *page) | ^~~~~~~~~~~~~~ Fix this by moving dump_emit_page() inside the existing section protected by #ifdef CONFIG_ELF_CORE.
