ecryptfs_miscdev_release(9)

💅 ecryptfs_miscdev_release — the kernel API manual, bestie edition ✨

okay so real talk, this one lives in the Kernel API Manual section, and it's genuinely such a little guy. tiny function, big responsibilities. let's get into it 🫶

---

✨ NAME ✨

ecryptfs_miscdev_release — literally just the release handler for the eCryptfs misc device, no cap. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int ecryptfs_miscdev_release (struct inode *inode , struct file *file );

like, the signature is right there, mwah. 💋

---

🦋 ARGUMENTS 🦋

• inode — this is the inode of the fs/ecryptfs/euid handle. and bestie… it gets ignored. not even looked at. it's giving background character energy, honestly. 💀
• file — this one actually matters! it's the file for the fs/ecryptfs/euid handle. main character, obviously. 👑

---

🧚 DESCRIPTION 🧚

so here's the tea ☕ — this function keeps the daemon registered. like, it holds on. and it keeps holding on until either:

• the daemon sends another ioctl to fs/ecryptfs/ctl, or
• the kernel module unregisters.

whichever comes first, periodt. 💅

and the return situation? iconic and simple:

• returns zero on success ✨
• returns non-zero otherwise 😭

that's it, that's the whole function, and honestly? we love a low-drama king. 🔥
