💅 probe::nfs.fop.lock — NFS client file lock operation ✨

okay bestie, so this is a page from Network File Storage Tapsets — it's PROBE::NFS.FOP.L(3stap), section 3stap, and it's giving very specific, very useful energy. let's get into it 🫶

✨ NAME ✨

probe::nfs.fop.lock — the NFS client file lock operation probe. it's exactly what it says on the tin, no cap. 🔒

---

🌸 SYNOPSIS 🌸

probe nfs.fop.lock {}

that's it. that's the whole probe. she's simple, she's elegant, she ate. 👑

---

🦋 VALUES 🦋

okay so when this probe fires, you get a whole lil goodie bag of values. here's every single one, don't skip any, they all matter 💖

• i_mode — the file type AND the access rights. two-for-one, iconic.
• ino — the inode number. her government name fr fr.
• lock_type — what kind of lock we're dealing with.
• cmd — the cmd arguments. yeah, that's the description, we don't make the rules around here 😭
• dev — the device identifier. which device is she living on?
• lock_flags — the lock flags. flags on flags on flags 🚩
• lock_end — the ending offset of the locked region. where the lock stops.
• lock_start — the starting offset of the locked region. where the lock begins.

so like, lock_start to lock_end is the lil slice of the file that's locked down. the range. the moment. 💅
