Good point, no RMV could occur before it is implemented, however a dedicated
commit for the fix itself (i.e. alarm callback not supposed to end up
calling ibv_get_async_event()) might better explain the logic behind these
changes. What I mean is, if there was no problem, you wouldn't need to make
priv_link_status_update() a separate function, right?

I understand, this could also have been part of the commit log of the
dedicated commit.

Thanks.
