[Xen-devel] Error when compiling the block device tap driver

[Guillaume Thouvenin <guillaume.thouvenin@xxxxxxxx>]

Hello,

 When the block tap driver is selected in linux-2.6.16.13-xen (Xen --->
Block device tap driver) it produces an error during the compilation. I
see the problem but I'm not sure about how to fix it. So I copy the
error. I'm using xen-3.0-testing.hg
