This is currently a warning, but I think modpost should stop building in this case. If the same symbol is exported multiple times and we let it keep going, the sanity check becomes difficult. Only the legitimate case is that an external module overrides the corresponding in-tree module to provide a different implementation with the same interface. Also, there exists an upstream example that exploits this feature. $ make M=tools/testing/nvdimm ... builds tools/testing/nvdimm/libnvdimm.ko. This is a mocked module that overrides the symbols from drivers/nvdimm/libnvdimm.ko. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com> |
