libie_debugfs_enable_write(9)

💅 libie_debugfs_enable_write — the kernel API manual, bestie edition ✨

Okay so like… hi. Welcome to the libie_debugfs_enable_write(9) page from the Kernel API Manual (section 9, obviously, we're in the grown-up kernel docs). This is the write side of the enable file and she's doing exactly one job: letting userspace write into that file. Iconic, honestly. 🎀

✨ NAME ✨

libie_debugfs_enable_write — write into the 'enable' file 🫶

Periodt. That's the whole vibe. If you came here looking for the read girlie, she's got her own page (scroll down to SEE ALSO, babes).

---

🌸 SYNOPSIS 🌸

ssize_t libie_debugfs_enable_write (struct file *filp , const char
       __user *buf , size_t count , loff_t *ppos );

Look at her. Four arguments, returns a ssize_t, that's the classic write-handler silhouette 💅 — she's literally serving file-operations energy. Standard, no cap.

💖 ARGUMENTS 💖

Bestie, let's meet the cast 🧚:

• filp — the opened file. Like, the file that got opened. That one. She's the main character here. 👑
• buf — where to find the user's data. It's const char __user *, so it's the user's side of the pool and you lowkey can't just dereference it however you want, iykyk. 🦋
• count — the length of the user's data. A size_t, so she's a big girl and she's unsigned. 🌈
• ppos — file position offset. It's a loff_t *, so it's a pointer to where we are in the file. Classic. ⭐

Not me being obsessed with the fact that all four of these are just handed to you by the VFS. You didn't have to do anything. She just arrives. 😭

And that's the page! 💜

Cute little sign-off for the girlies who read to the bottom: this one comes to you from the source ./drivers/net/ethernet/intel/l... (yes, the line was truncated in the original, and yes, I'm keeping it exactly like that — character for character, bestie, that's the rule 🙈), dated October 2026, and she is filed under libie_debugfs_enable_write(9) in the Kernel API Manual. Slay. 💅✨
