Drop modpost command line switches that are no longer used by makefile.modpost, upon request from Sam Ravnborg <sam@xxxxxxxxxxxx>, who wrote: modpost is not supposed to be used outside the kernel build. [...] I checked if there were any options supported by modpost that was not configurable in makefile.modpost. And I could see that the -M and -K options in getopt() was leftovers. The code that used these option was was dropped in: commit a8773769d1a1 ("Kbuild: clear marker out of modpost") Could you add a patch that delete these on top of what you already have. https://lore.kernel.org/lkml/20181020140835.GA3351@xxxxxxxxxxxx/ Cc: Sam Ravnborg <sam@xxxxxxxxxxxx> Cc: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx> Cc: Michal Marek <michal.lkml@xxxxxxxxxxx> Cc: linux-kbuild@xxxxxxxxxxxxxxx Cc: linux-kernel@xxxxxxxxxxxxxxx Signed-off-by: Paul Walmsley <paul.walmsley@xxxxxxxxxx> Signed-off-by: Paul Walmsley <paul@xxxxxxxxx> --- scripts/mod/modpost.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/scripts/mod/modpost.c b/scripts/mod/modpost.c index 0d998c54564d..85bd93c63180 100644 --- a/scripts/mod/modpost.c +++ b/scripts/mod/modpost.c @@ -2416,7 +2416,7 @@ int main(int argc, char **argv) struct ext_sym_list *extsym_iter; struct ext_sym_list *extsym_start = NULL; - while ((opt = getopt(argc, argv, "i:I:e:mnsST:o:awM:K:E")) != -1) { + while ((opt = getopt(argc, argv, "i:I:e:mnsST:o:awE")) != -1) { switch (opt) { case 'i': kernel_read = optarg; -- 2.19.1
