seq_release(9)

💖 seq_release(9) 💖

okay so this is the seq_release(9) page from the Kernel API Manual, and it's literally the cleanup bestie for sequential files. no cap, it's short but it matters. 🫶

---

✨ NAME ✨

seq_release — free the structures associated with sequential file.

---

🌸 SYNOPSIS 🌸

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

---

🎀 ARGUMENTS 🎀

• inode — its inode. like, the inode it belongs to, periodt.
• file — file in question. bestie, it's the file in question. 💅

---

🦋 DESCRIPTION 🦋

This one frees the structures associated with sequential file. yes ma'am, cleanup duty. 🧹✨

You can use it as ->f_op->release if you don't have private data to destroy.

lowkey important caveat: that ->f_op->release move only works if you don't have private data to destroy. don't skip that part, bestie. 💀
