flock_lock_inode_wait(9)

💅 flock_lock_inode_wait(9) — from the Kernel API Manual, bestie ✨

okay so you found a kernel API manpage and you're like "what is this even" — don't worry, I got you. This is flock_lock_inode_wait, straight out of the Kernel API Manual, and it's honestly not that deep. Let's go 🫶

---

🌸 NAME 🌸

flock_lock_inode_wait — apply a FLOCK-style lock to a file. that's it. that's the whole vibe 💅

---

✨ SYNOPSIS ✨

int flock_lock_inode_wait (struct inode *inode , struct file_lock *fl );

like, it returns an int, it takes two pointers, we move 💖

---

🎀 ARGUMENTS 🎀

• inode — the inode of the file you're applying the lock to. the actual target, the main character 👑
• fl — the lock that's getting applied. this is the lock itself, not a copy, not a vibe, the lock 🦋

---

🔥 DESCRIPTION 🔥

okay so real talk: this function applies a FLOCK-style lock request to an inode. that's literally the whole description, no notes, it ate and left no crumbs 💀✨

ngl the manpage is kinda quiet on the details here — no extra behaviour, no caveats, just "apply a FLOCK style lock request to an inode." so that's what we're working with, fr fr 🙈
