2.6.15-rc1: NET_CLS_U32 not working?

[Christian]

hi,

i noticed that some of my QoS rules are not working any more. oh, i 
forgot to enable CONFIG_NET_CLS_U32. but when enabled, i got the 
following errors when compiling / installing the module:

* Warning: "unregister_tcf_proto_ops" [net/sched/cls_u32.ko] undefined!
* Warning: "register_tcf_proto_ops" [net/sched/cls_u32.ko] undefined!
* Warning: "tcf_exts_dump" [net/sched/cls_u32.ko] undefined!
* Warning: "tcf_exts_dump_stats" [net/sched/cls_u32.ko] undefined!
* Warning: "tcf_exts_change" [net/sched/cls_u32.ko] undefined!
* Warning: "tcf_exts_validate" [net/sched/cls_u32.ko] undefined!
* Warning: "tcf_exts_destroy" [net/sched/cls_u32.ko] undefined!

modprobe...

cls_u32: Unknown symbol unregister_tcf_proto_ops
cls_u32: Unknown symbol tcf_exts_destroy
cls_u32: Unknown symbol tcf_exts_change
cls_u32: Unknown symbol tcf_exts_dump
cls_u32: Unknown symbol tcf_exts_dump_stats
cls_u32: Unknown symbol register_tcf_proto_ops
cls_u32: Unknown symbol tcf_exts_validate
cls_u32: Unknown symbol unregister_tcf_proto_ops
cls_u32: Unknown symbol tcf_exts_destroy
cls_u32: Unknown symbol tcf_exts_change

cls_u32: Unknown symbol tcf_exts_dump_stats
cls_u32: Unknown symbol register_tcf_proto_ops
cls_u32: Unknown symbol tcf_exts_validate

when i disabled CONFIG_NET_CLS_U32, everything compiles fine, but 
cls_u32 is missing of course :-(

all the missing symbols seem to be defined in include/net/pkt_cls.h. but 
 this file is #included by net/sched/cls_u32.c and other too, so i 
don't really know, why it doesn't work.

FWIW, i see EXPORT_SYMBOLs at the very end of net/sched/cls_api.c, but i 
can't see if/when cls_api.c is used (included?) at all.

undoing the PKT_SCHED patch [1] does not really help. the config-file is 
a bit different due to CONFIG_NET_QOS, the errors don't go away.

.config, .config.diff, dmesg, verbose output and more is here:

thanks for looking into that,
Christian.
