Re: [Xen-devel] how to use the xen functions
Sorry, I tried your suggestion, but still have the same problem. :(
After I add the export code, I did "make ARCH=xen linux24" and "make
install". Looks like the /lib/module/2.4.27-xen0 was updated. But I still
get the same error message.
Here is the dump from
command "grep ctrl_if_send_message_block /proc/ksyms"
c01b2a30 ctrl_if_send_message_block_R__ver_ctrl_if_send_message_block
This output is DIFFERENT from a successfully exported symbol:
grep create_xen_proc_entry /proc/ksyms
c0326f10 create_xen_proc_entry_Ra770fe56 (Ra770fe56 is the R+version
hash, right?), why ctrl_if_send_message_block has a weird
ctrl_if_send_message_block_R__ver_ctrl_if_send_message_block?
If I do "nm vmlinux |grep ctrl_if_send_message_block"
I got:
c01b2a30 T ctrl_if_send_message_block
c0376980 R __kstrtab_ctrl_if_send_message_block
c0386868 R __ksymtab_ctrl_if_send_message_block
Any further idea on this?
Thanks,
-x
