Hello,

I am new to Linux kernel development and I want to learn how to read
and understand the existing kernel source code.

Could you please suggest:
- Where a beginner should start reading the kernel code
- Which subsystems or files are good for first-time learners
- Any documentation or guides that help understand the code structure

Thank you for your time and guidance.

Regards,
