Anthony PERARD 705be57094 xen-bus: Avoid rewriting identical values to xenstore ... When QEMU receives a xenstore watch event suggesting that the "state" of the frontend changed, it records this in its own state but it also re-write the value back into xenstore even so there were no change. This triggers an unnecessary xenstore watch event which QEMU will process again (and maybe the frontend as well). Also QEMU could potentially write an already old value.
