arch_param_cb (name , ops , arg , perm );

🎀 ARGUMENTS 🎀

• name — a valid C identifier which is the parameter name. iconic little identifier behavior 💅
• ops — the set & get operations for this parameter. the whole get/set situation 🫶
• arg — args for ops. yes, exactly that ✨
• perm — visibility in sysfs. the sysfs visibility vibe check 👑
