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
