posix_lock_inode_wait(9)

💅 posix_lock_inode_wait(9) 💅

okay so this is a page from the Kernel API Manual, bestie — like, the actual kernel docs, not a vibes-only summary. sit down, hydrate, and let's get into it 🫶

---

✨ NAME ✨

posix_lock_inode_wait — apply a POSIX-style lock to a file 🔒

---

✨ SYNOPSIS ✨

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

like, that's the whole signature. two args, one int back. no cap. 🎀

---

✨ ARGUMENTS ✨

• inode — the inode of the file you're trying to slap that lock onto. like, the actual file object in the kernel's little filing cabinet 📁
• fl — the lock itself. the thing being applied. the main character of this whole operation 👑

---

✨ DESCRIPTION ✨

so what it does: it applies a POSIX style lock request to an inode. that's it, that's the whole description, and honestly? iconic. short, sweet, gets straight to the point. no rambling, no filler, just lock-application realness ✨

ngl the original page is very light on the details here — I'm not gonna invent lore that isn't in the source. what you see is what you get 💀
