Actually, this doesn't even compile, so I've reverted: [davem@dhcp-10-15-49-227 net-next]$ make -s -j16 In file included from net/dccp/trace.h:105:0, from net/dccp/proto.c:42: ./include/trace/define_trace.h:89:42: fatal error: ./trace.h: No such file or directory #include TRACE_INCLUDE(TRACE_INCLUDE_FILE) ^ compilation terminated.

Hmm, strange. I could compile it on x86-64 and i386. Let me check what was wrong. Thanks,

Hi David, Could you share your .config file? I would like to reproduce it.

I don't see a modification of the Makefile to get the trace.h file you created. Shouldn't there be something like: CFLAGS_proto.o := -I$(src) in the Makefile? -- Steve

Oops, I didn't do that, but also I had committed all in this changeset. Hmm, strange, because I don't see same issue... At first I will try to reproduce it and try above flags again. Thank you,

I could reproduce it with kallmodconfig. And when I add below diff, it is resolved. If I built with O=<dir> option, it didn't happen. diff --git a/net/dccp/Makefile b/net/dccp/Makefile index 9d0383d2f277..8d4a8e901ae0 100644 --- a/net/dccp/Makefile +++ b/net/dccp/Makefile @@ -25,3 +25,5 @@ obj-$(CONFIG_INET_DCCP_DIAG) += dccp_diag.o dccp-$(CONFIG_SYSCTL) += sysctl.o dccp_diag-y := diag.o + +CFLAGS_proto.o := -I$(src) I'll update [5/6].
