When a task is being enqueued outside wakeup path, ops.select_cpu() isn't called, so we can end up in a situation where a newly enqueued task keeps waiting in one of the DSQs while there are idle CPUs. Factor out idle CPU selection path into pick_idle_cpu() and call it from the enqueue path in such cases. This problem is shared across schedulers and likely needs a more generic solution in the future. |

RUST SCHEDULERS
Introduction
This directory contains schedulers with user space rust components.
The README in each scheduler directory provides some background and describes the types of workloads or scenarios they're designed to accommodate. For more details on any of these schedulers, please see the header comment in their main.rs or *.bpf.c files.
