Make restart handling with user_exit_info simpler and consistently use the load and report macros consistently across the rust schedulers. This makes all schedulers automatically handle auto restarts from CPU hotplug events. Note that this is necessary even for scx_lavd which has CPU hotplug operations as CPU hotplug operations which took place between skel open and scheduler init can still trigger restart. |

scx_rlfifo
This is a single user-defined scheduler used within sched_ext, which is a Linux kernel feature which enables implementing kernel thread schedulers in BPF and dynamically loading them. Read more about sched_ext.
Overview
scx_rlfifo is a simple FIFO scheduler runs in user-space, based on the scx_rustland_core framework.
Typical Use Case
This scheduler is provided as a simple template that can be used as a baseline to test more complex scheduling policies.
Production Ready?
Definitely not. Using this scheduler in a production environment is not recommended, unless there are specific requirements that necessitate a basic FIFO scheduling approach. Even then, it's still recommended to use the kernel's SCHED_FIFO real-time class.
