<pre wrap="">Not sure I see the need to duplicate the alloc->id value especially
since it's "invalid" have "resctrl->alloc == NULL", right?
Can this resctrl->id ever be different? Not that I can see. I see this
is a desire to reduce an error case in Format processing, but if
virResctrlAllocGetID returned NULL there's other problems...

This patch should be removed and will be removed.<br>
<br>
It is introduced in series v4, in that series the
'resctrl->alloc' is allowed<br>
to be NULL representing a default monitor. <br>
Now we changed our design and resctrl->alloc is always assigned
with an<br>
virResctrlAlloc data structure, then 'resctrl->id' is not
necessary. We can keep the<br>
resctrl ID in alloc->id.<br>
<br>
Thanks for review.<br>
