I think the right solution for these pre/post vectors is to _NOT_ mark

Yes, agreed. Marking the pre/post vector as managed was a mistake
(and I don't think it even was intentional, at least on my part).
Got it !
And, I am trying to fix this by:
-Don't set affinity for pre/post vectors in
irq_create_affinity_masks().
-And do not setup the desc->affinity of pre/post vectors in
alloc_msi_entry().
So, the affinity in alloc_descs() will be NULL, and the interrupt won't
be marked as IRQD_AFFINITY_MANAGED.
Is it OK? and I will show the codes after testing it.
Thanks,
