[Xen-devel] how to use the xen functions

[Xin Zhao <zhaoxin@xxxxxxxxxxxxxx>]

I need to use the function "ctrl_if_send_message_block" in my kernel
module running in Dom0. This function  is provided
in 2.6.9-sparse/arch/xen/kernel/ctrl_if.c, however, when I tried to insert
the
module, I got the error message "unresolved symbol
ctrl_if_send_message_block". Looks like the function is not exported. So I
go to 2.6.9-sparse/arch/xen/kernel/ctrl_if.c to add the following line:

EXPORT_SYMBOL(ctrl_if_send_message_block);

But after compilation and reboot, I still got the same error message. Can
someone give me some advice on how to use xen provided functions?


Thanks a lot.

Xin
