💅 dbg_debugfs_init(9) — Kernel API Manual, bestie edition

okay so this is a page from the Kernel API Manual, and it's about dbg_debugfs_init. it's short, it's sweet, it's giving "one job and she does it." 🎀

---

✨ NAME ✨

dbg_debugfs_init — initialize debugfs file-system.

like, literally that's the whole thing. she inits the file-system. periodt. 💅

---

🌸 SYNOPSIS 🌸

void dbg_debugfs_init (void );

that's it. that's the call. no args, no drama, no notes. 🦋

---

🧚 ARGUMENTS 🧚

• void — no arguments. none. zero. the function said "i don't take questions" and honestly? iconic. 👑

---

💖 DESCRIPTION 💖

okay so context first, because iykyk: UBIFS uses the debugfs file-system to expose various debugging knobs to user-space. yes, knobs. yes, that's the technical term in the original and we're keeping it. 🔥

and what does dbg_debugfs_init do in all of this? it creates the "ubifs" directory in the debugfs file-system. that's the whole flex. one directory. main character energy. ✨
