In some cases, it might be desirable to package a module from an external source tree alongside the base kernel. In those cases, it might also be desirable to not have those modules tainting the kernel. This patch provides a mechanism for an external module build to declare itself as an "integrated build". Such a module is then treated the same as an intree module. Signed-off-by: John W. Linville <linville@xxxxxxxxxxxxx> --- Any thoughts on this? I'm thinking of adding this to Fedora kernels, where I have been working to integrate the compat-wireless package as part of the base kernel RPM. scripts/Makefile.modpost | 1 + scripts/mod/modpost.c | 10 ++++++++-- 2 files changed, 9 insertions(+), 2 deletions(-) diff --git a/scripts/Makefile.modpost b/scripts/Makefile.modpost index 08dce14..160c6fb 100644 --- a/scripts/Makefile.modpost +++ b/scripts/Makefile.modpost @@ -81,6 +81,7 @@ modpost = scripts/mod/modpost \ $(if $(KBUILD_EXTMOD),-o $(modulesymfile)) \ $(if $(CONFIG_DEBUG_SECTION_MISMATCH),,-S) \ $(if $(KBUILD_EXTMOD)$(KBUILD_MODPOST_WARN),-w) \ + $(if $(INTEGRATED_BUILD),-B) \ $(if $(cross_build),-c) quiet_cmd_modpost = MODPOST $(words $(filter-out vmlinux FORCE, $^)) modules diff --git a/scripts/mod/modpost.c b/scripts/mod/modpost.c index 2bd594e..5d077f9 100644 --- a/scripts/mod/modpost.c +++ b/scripts/mod/modpost.c @@ -43,6 +43,9 @@ static int warn_unresolved = 0; static int sec_mismatch_count = 0; static int sec_mismatch_verbose = 1; +/* Is this a module being built as part of an integrated package? */ +static int integrated_build = 0; + enum export { export_plain, export_unused, export_gpl, export_unused_gpl, export_gpl_future, export_unknown @@ -1851,7 +1854,7 @@ static void add_header(struct buffer *b, struct module *mod) static void add_intree_flag(struct buffer *b, int is_intree) { - if (is_intree) + if (is_intree || integrated_build) buf_printf(b, "\nMODULE_INFO(intree, \"Y\");\n"); } @@ -2101,7 +2104,7 @@ 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:cmsSo:awM:K:")) != -1) { + while ((opt = getopt(argc, argv, "i:I:e:cmsSo:awM:K:B")) != -1) { switch (opt) { case 'i': kernel_read = optarg; @@ -2139,6 +2142,9 @@ int main(int argc, char **argv) case 'w': warn_unresolved = 1; break; + case 'B': + integrated_build = 1; + break; default: exit(1); } -- 1.7.4.4 -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
