--- Comment #9 from Conrad Meyer <cem@freebsd.org> ---
(In reply to Andriy Gapon from comment #8)
Yes, performance of add/remove doesn't matter.  But performance of
intr_event_handle() matters very much, and adding a contested spin lock to =
it
seems like a bad idea.  I suppose it only needs to be taken for shared
interrupts, not MSI, so maybe the impact is not so bad.
