problem of build and install blktap2 module

Hi,all:
I got warning messages as this :  WARNING: "xen_multi_update_va_mapping"
[drivers/xen/blktap2/blktap.ko] undefined!  when I tried to build the
blktap2 module. I can see that in linux-2.6.27 lots of changes in file
arch/i386/mm/hypervisor.c, but "xen_multi_update_va_mapping " is not used in
the blktap2 module. I don't know why this warning appeared. Can any body
help me? 
    And if I insert the module blktap.ko that I build out, the system told
me "insmod: error inserting 'blktap.ko': -1 Unknown symbol in module
 " . It made me creazy . Kind if you can give me any suggestion. 
Thanks,
Lyman

You might want to take a look at XCP or XCI dom0 kernels. 
They're based on SLES11 2.6.27, and they both have blktap2 already
backported.

答复: ??????: [Xen-devel] problem of build and install blktap2 module

[fanliang]

Thanks for the reply!  My blktap2source codes came from  XCP dom0 kernel. I still got the message:WARNING: "xen_multi_update_va_mapping"
 [drivers/xen/blktap2/blktap.ko] undefined!
