Re: [PATCH linux-next 2/3] tools/delaytop: add flexible sorting by delay field

> The original delaytop only supported static output with limited

> Adds real-time interactive controls through keyboard input:
> 1) Add interactive menu system with visual prompts
> 2) Support dynamic sorting changes without restarting
> 3) Enable toggle of memory verbose mode with 'M' key

> The interactive mode transforms delaytop from a static monitoring tool

> view in real-time based on observed performance patterns.
