Re: [Xen-devel] [Xen-dev][PATCH] fix qcow2 can not work with blktap2
Rather than patching blktap2/daemon/, let's just cut it entirely.
Blktap2 doesn't need to be replacing blktapctrl or tapdisk. These
shouldn't have been included in the blktap2 release - we were just being a
little over-zealous in mirroring Citrix's blktap2. So those can be
exclusive to the original blktap.
I'll send a counter-proposal patch.

Since the hotplug script for udev has been removed by c/s 19349, we need report
the hotplug-status while the corresponding tapdisk been create. Or else, It will
raise an error "hotplug script not working".
