Note that it wont build in your tree, because the TRACE_EVENT_TEMPLATE /
DEFINE_EVENT facility this relies on is not upstream yet.
The events are not affected in any way (and block/* is not modified) -
it's just a more efficient representation of the same. I've applied them
to -tip, to keep the facility and dependent updates in a single place.
