debugfs_create_x16(9)

📦 version 7.3.1, in nixpkgs unstable

💖 debugfs_create_x16(9) 💖

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, and yes we're gonna read it together like it's the group chat 🫶 this one's literally called debugfs_create_x16, and it's the little function that makes a debugfs file where you can read and write an unsigned 16-bit value. lowkey iconic.

✨ NAME ✨

debugfs_create_x16 — create a debugfs file that is used to read and write an unsigned 16-bit value 🌸

🦋 SYNOPSIS 🦋

void debugfs_create_x16 (const char *name , umode_t mode , struct dentry
*parent , u16 *value );

look at her. four arguments, zero drama. 💅 (ok maybe a little drama, the line wrapped, don't come for me.)

🎀 ARGUMENTS 🎀

  • name — a pointer to a string containing the name of the file to create. you know, the glow-up nameplate for your file ✨
  • mode — the permission that the file should have. yes queen, set your boundaries 🔥
  • parent — a pointer to the parent dentry for this file. this should be a directory dentry if set. if this parameter is NULL, then the file will be created in the root of the debugfs filesystem. so like, NULL = no parent, you're on your own main character energy, straight to the root of debugfs 👑
  • value — a pointer to the variable that the file should read to and write from. the file's basically in a situationship with this variable. two-way. 🫶
ngl bestie, value is the whole point — that's the variable the debugfs file reads from and writes to. no cap.

like a whole squad of debugfs creators and friends. x16 is the middle child but she ate anyway 💅

and that's the page bestie!! 🎀 source vibes come from ./fs/debugfs, dated October 2026, and yes — the header was debugfs_create_x16(9), the manual was Kernel API Manual, and now you're fully caught up. mwah 💜✨🦋
