Subject: [PATCH] sd-event: remove earliest_index/latest_index into common part
|
|
of event source objects
|
|
|
|
So far we used these fields to organize the earliest/latest timer event
|
|
priority queue. In a follow-up commit we want to introduce ratelimiting
|
|
to event sources, at which point we want any kind of event source to be
|
|
able to trigger time wakeups, and hence they all need to be included in
|
|
the earliest/latest prioqs. Thus, in preparation let's make this
|
|
generic.
|
|
|
|
No change in behaviour, just some shifting around of struct members from
|
|
the type-specific to the generic part.
|
|
|
|
(cherry picked from commit f41315fceb5208c496145cda2d6c865a5458ce44)
