Previously,
Inject
was defined inruntime::task
. This was because it used some internal fns as part of the intrusive linked-list implementation.In the future, we want to remove the mutex from Inject and move it to the scheduler proper (to reduce mutex ops). To set this up, this commit moves
Inject
toruntime::scheduler
. To make this work, we have topub(crate)
task::RawTask
and use that as the interface to access the next / previous pointers.
