debugfs_remove(9)

💅 debugfs_remove — the Kernel API Manual, bestie edition 🎀

okay so you're reading the debugfs_remove(9) page, which means you're deep in kernel land and honestly? proud of you. this is the manual that tells you how to take out the trash in debugfs. let's go ✨

---

🌸 NAME

debugfs_remove — recursively removes a directory. yes bestie, recursively. the whole tree. gone. 💀

---

🦋 SYNOPSIS

void debugfs_remove (struct dentry *dentry );

that's it. one argument. one function. one vibe check. 🫶

---

✨ ARGUMENTS

• dentry — a pointer to a the dentry of the directory to be removed. (yes, the original says "a pointer to a the dentry" — we love a typo queen 👑, keeping it exactly as-is.) if this parameter is NULL or an error value, nothing will be done. zero. nada. the function just looks at you and shrugs. 🙈

---

💖 DESCRIPTION

so here's the tea: this function recursively removes a directory tree in debugfs that was previously created with a call to another debugfs function (like debugfs_create_file or variants thereof.) like, it goes in and clears the whole thing, no crumbs left. 🧹✨

and this part is important, so listen up: this function is required to be called in order for the file to be removed. no automatic cleanup of files will happen when a module is removed — you are responsible here. that's right, you. no one's coming to save you, no little garbage-collector fairy is gonna swoop in. 🧚 nope. if you don't call it, it stays. main character energy = main character responsibility, iykyk. 😭

seriously though — if you skip this, your debugfs files just sit there being messy forever. not iconic. call the function. 💅
