hujun260 opened a new pull request, #14865:
URL: https://github.com/apache/nuttx/pull/14865

   ## Summary
   remove up_set_current_regs/up_current_regs
   reason:
   up_set_current_regs initially had two functions:
   
   1: To mark the entry into an interrupt state.
   2: To record the context before an interrupt/exception. If we switch to
      a new task, we need to store the upcoming context regs by calling 
up_set_current_regs(regs).
   
   Currently, we record the context in other ways, so the second function is 
obsolete. Therefore, we need to rename up_set_current_regs to better reflect 
its actual meaning, which is solely to mark an interrupt.
