__devlink_s...id_increment(9)

💅 __devlink_snapshot_id_increment — like, the whole vibe

okay so bestie, welcome to the Kernel API Manual ✨ this one's from the ./net/devlink corner of the kernel and she's a lil helper function with main character energy 👑

---

✨ NAME ✨

__devlink_snapshot_id_increment — increments the number of snapshots that are using a given id 🎀

yes literally that's it, that's the whole job, and she does it flawlessly 💅

---

🌸 SYNOPSIS 🌸

int __devlink_snapshot_id_increment (struct devlink *devlink , u32 id );

---

🦋 ARGUMENTS 🦋

• devlink — the devlink instance 🫶 (you know, the one doing the snapshotting)
• id — the snapshot id 💖

---

🌈 DESCRIPTION 🌈

okay so here's the tea ☕ — this function keeps track of when a new snapshot starts using an id. The way it works is honestly iconic: it loads the count for the given id out of the snapshot xarray, increments it, and stores it right back. Load → bump → store. periodt 💀✨

It gets called when a new snapshot is created with the given id. So every time somebody rolls up with that id, the count goes up by one 🔥

⚠️ bestie listen to me — the id must have been previously allocated by devlink_region_snapshot_id_get. No cap. Don't be out here passing random ids, that's not the vibe 🙈

It returns 0 on success, or an error on failure. Simple as that, slay 💅
