securityfs_remove(9)

💅 securityfs_remove — the Kernel API Manual page, but make it cute

okay so real talk, this is securityfs_remove(9) from the Kernel API Manual, and it's basically the "girl, clean up after yourself" of securityfs. let's get into it ✨

---

🌸 NAME 🌸

securityfs_remove — removes a file or directory from the securityfs filesystem. that's it, that's the whole job. iconic honestly.

---

🎀 SYNOPSIS 🎀

void securityfs_remove (struct dentry *dentry );

no return value bestie, it's void — it just does the thing and leaves. main character energy fr 💅

---

💖 ARGUMENTS 💖

• dentry — a pointer to a the dentry of the file or directory to be removed. (yes, "a the", that's how the original says it, I don't make the rules 🙈) so basically: hand it the dentry of the thing you want gone, and it handles it.

---

🦋 DESCRIPTION 🦋

so this function removes a file or directory in securityfs that was previously created with a call to another securityfs function (like securityfs_create_file or variants thereof.) like, you made it, now you unmake it. balance. ✨

💀 important: 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. the kernel will not do your chores for you, bestie. nobody's coming to save you. you made the file, you delete the file. that's the vibe check and you failed it if you forget. 😭

AV: when applied to a directory it will take all children out; no need to call it for descendents if the ancestor is getting killed. so like, if you're taking out the whole family tree, don't bother going branch by branch — take the ancestor and the children come with it. efficiency slay. 🧚‍♀️
