[openib-general] [PATCH] IB/core: fix SM LID/LID change with client reregisterset

[Michael S. Tsirkin]

Quoting r. Hal Rosenstock <halr at voltaire.com>:
> Are these two events equivalent ? e.g. does LID change require
> reregistration ? (That's a potential overhead as well). 

Client reregistration support is an optional SM feature

> What about deregistration of the old registrations when this occurs ?
> Is that handled ?

???
sa_query and cache do not have any old registrations
