Hi, Tejun,

In 2.6.30 and later, If I want to support hotplug, but host controller
does not support hotplug via interrupt. The best way is to patch your
hotplug polling patchset.
I did not see this patch merged in mainline. Is there other new way to
handle this type of hotplug now?

Hmmm... Unfortunately, no.  Now that most modern controllers support
proper hotplug the pressure for hotplug-by-polling is much lower, so
it kind of got dropped.

Thanks.
