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

> From: Fan Yu <fan.yu9@....com.cn>
> 
> The original delaytop only supported static output with limited
> interaction. Users had to restart the tool with different command-line
> options to change sorting or display modes, which disrupted continuous
> monitoring and reduced productivity during performance investigations.
> 
> 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
> into a dynamic investigation platform, allowing users to adapt the
> view in real-time based on observed performance patterns.
