modpost: add PATTERNS() helper macro
This will be useful to define a NULL-terminated array inside a function call. Currently, string arrays passed to match() are defined in separate places: static const char *const init_sections[] = { ALL_INIT_SECTIONS, NULL }; static const char *const text_sections[] = { ALL_TEXT_SECTIONS, NULL }; static const char *const optim_symbols[] = { "*.constprop.*", NULL }; ... /* Check for pattern 5 */ if (match(fromsec, text_sections) && match(tosec, init_sections) && match(fromsym, optim_symbols)) return 0; With the new helper macro, you can list the patterns directly in the function call, like this: /* Check for pattern 5 */ if (match(fromsec, PATTERNS(ALL_TEXT_SECTIONS)) && match(tosec, PATTERNS(ALL_INIT_SECTIONS)) && match(fromsym, PATTERNS("*.contprop.*"))) return 0; Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
