free_irq_vector on ia64
Hi Alex:
I was looking at an ia64 bug report and noticed that we don''t
actually free IRQs in the free_irq_vector hypercall. This
would eventually lead to alloc_irq_vector failing. Unless I''m
mistaken something like calling pci_disable_device and
pci_enable_device can lead to this situation.
So I''m wondering what the original problem was and how could
we resolve it without leaking the IRQ. Any ideas?
Thanks,
