debugfs_create_x8(9)

💅 debugfs_create_x8 — the Kernel API Manual, but make it cute

okay so bestie, welcome to debugfs_create_x8(9) 🌸 this is the Kernel API Manual page for it, and honestly it's giving "tiny function, huge friend group" energy. Let's get into it ✨

✨ NAME ✨

debugfs_create_x8 — makes a debugfs file that you can read from and write to, and it's wired up to an unsigned 8-bit value 🎀

🦋 SYNOPSIS 🦋

void debugfs_create_x8 (const char *name , umode_t mode , struct dentry
*parent , u8 *value );

no cap, that's the whole signature. look at her go 💜

👑 ARGUMENTS 👑

• name — a pointer to a string holding the name of the file you wanna create, bestie. that's the vibe check for what shows up in debugfs ✨
• mode — the permission that the file should have. like, who's allowed in the group chat 🔥
• parent — a pointer to the parent dentry for this file. this should be a directory dentry if you set it. and if this parameter is NULL, then the file gets created in the root of the debugfs filesystem — no parent, no problem, main character energy fr fr 🌈
• value — a pointer to the variable that the file should read to and write from. so the file is literally just a little window into that variable 🫶
