configfs_create_dir(9)

✨ configfs_create_dir (Kernel API Manual, bestie!!) ✨

Okay so real talk, this one is a function in the Linux kernel API manual and it's literally the "make a directory for your config_item" moment. Yes bestie, we're doing filesystem directory creation today 💅

---

🌸 NAME 🌸

configfs_create_dir — create a directory for an config_item. That's it, that's the whole name section, she's simple and she's iconic 🎀

---

🦋 SYNOPSIS 🦋

int configfs_create_dir (struct config_item *item , struct dentry
*dentry , struct configfs_fragment *frag );

The way that signature just sits there with three pointer args and an int return… main character energy fr fr 🔥

---

💖 ARGUMENTS 💖

• item — the config_item we're creating a directory for. Like, this is the whole point of the call, she's the reason we're all here 👑
• dentry — the config_item's dentry. Yeah, the dentry that belongs to the item, hand it over 🫶
• frag — the config_item's fragment. That's the fragment, for the item. Keeping it real with you, that's the description, no cap 🌈

---

🌼 NOTE 🌼

Heads up bestie, this one matters: user-created entries won't be allowed under this new directory until it is validated by configfs_dir_set_ready. So like… it's not open for business yet, okay? Don't try it. Wait for the validation. No cap 😭
