module_param_named(9)

💅 module_param_named(9) — the Kernel API Manual, bestie edition ✨

okay so this page is from the Kernel API Manual, section 9, and the whole vibe is: making a module/cmdline parameter show up under a different name than the variable it lives in. iconic behavior tbh 🎀

---

🌸 NAME 🌸

module_param_named — a typesafe helper for a renamed module/cmdline parameter. fr fr, typesafe and renamed, we love a multitasker 💖

---

✨ SYNOPSIS ✨

module_param_named (name , value , type , perm );

that's the whole incantation, bestie — four args, no cap 👑

---

🫶 ARGUMENTS 🫶

• name — a valid C identifier which is the parameter name. yes, valid C identifier, the compiler is watching 👀
• value — the actual lvalue to alter. the real thing, the main character, the variable in question 💅
• type — the type of the parameter. gotta say what it is, iykyk 🔥
• perm — visibility in sysfs. this is how visible you want to be, which honestly same 🌈

---

🦋 DESCRIPTION 🦋

okay so listen. usually it's a good idea to have variable names and user-exposed names the same — like, matching names, cute, consistent, we stan 🥰

but that gets harder if the variable must be non-static, or if it's inside a structure. structures are not it, they play too much 😭

so this little helper allows exposure under a different name. that's the whole point. rename the vibe, keep the variable. periodt 💅✨

🌸 that's the page!! huge shoutout to ./include/linux for hosting all this, dated October 2026, and to the Kernel API Manual for the home. stay typesafe, stay renamed, mwah 💋🎀💖
