Without including ptlrpc_internal.h, GCC gives prototype warnings
"pack_generic.c:642:5: warning: no previous prototype for ..."
and sparse also complains "pack_generic.c:642:5: warning: symbol
'lustre_unpack_req_ptlrpc_body' was not declared. ..."

It does? What version of gcc give you that, I don't see that here.

Yes, but it's a non-default warning (-Wmissing-prototypes)
$ gcc --version
gcc (Gentoo 4.9.3 p1.0, pie-0.6.2) 4.9.3
When testing the above patch I've used Ubuntu Vivid Vervet's gcc
(also 4.9 I think, I don't have access to that machine right now).
To see the warn I'm adding "ccflags-y := -Wmissing-prototypes"
to a Makefile then "make SUBDIRS=..."
Hello!

Duh, so essentially it tells you that you have a non-static function
that lacks a previously defined prototype, but because it's
non-static, it's likely used elsewhere and the prototype might get
out of sync with the actual function definition?
I guess it's no big deal to include the ptlrpc_internal.h there
to catch potential problems like that.
Thanks.

Then you should say that, otherwise you have us worrying something is
really wrong with our build/compiler versions...
I've taken this patch, but next time please be more specific.
thanks,
