Lemme fill in the scheduler and locking/atomics bits as well:

Scheduler development takes place in the -tip tree, in the
sched/core branch - with occasional sub-topic trees for
work-in-progress patch-sets.

Locking development (including atomics and other synchronization
primitives that are connected to locking) takes place in the -tip
tree, in the locking/core branch - with occasional sub-topic
trees for work-in-progress patch-sets.
