ecryptfs_privileged_open(9)

💅 ecryptfs_privileged_open(9) 💅

okay so bestie, welcome to the kernel API manual, this one lives in section 9 and honestly? it's giving lowkey mysterious energy because the NAME line has literally no description after the dash. iconic of it. anyway, let's get into it 🎀

---

✨ NAME ✨

ecryptfs_privileged_open — yeah so the NAME section is literally just the function name and nothing else. no cap, that's the whole thing, the description slot is empty. we move 💅

---

🌸 SYNOPSIS 🌸

int ecryptfs_privileged_open (struct file **lower_file , struct dentry
*lower_dentry , struct vfsmount *lower_mnt , const struct cred *cred );

that's the whole signature, bestie, copy it exactly, don't you dare "fix" the spacing 😭

---

🦋 ARGUMENTS 🦋

• lower_file — this is where the result goes, specifically the result of dentry_open by root on the lower dentry. it's a struct file ** so yeah, double pointer, she's fancy 💅
• lower_dentry — the lower dentry for the file you're trying to open 🍓
• lower_mnt — the lower vfsmount for the file to open, matching energy to the dentry above ✨
• cred — the credential to use for this call. it's a const struct cred * so it's locked in, no edits 🙈

---

👑 DESCRIPTION 👑

so what does she actually do? this function gets a r/w file opened against the lower dentry 🔥 that's it, that's the whole vibe.

returns zero on success; non-zero otherwise ⭐ like, remember that, because zero = slay, non-zero = something went sideways 😭
