The current scheduled waiting queue uses VecQueue as the main data structure, which has these problems:

  1. The deletion efficiency is affected to a certain extent
  2. An additional state in wait queue field is introduced to improve the deletion efficiency.

In fact, Linux r4l now has a relatively mature List data structure, which I hope to introduce into ArceOS.
I have done related work on Starry before: refer to https://github.com/Starry-OS/linked_list/tree/main/src
