__devlink_re...pshot_create(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual, and today's main character is __devlink_region_snapshot_create 💅

✨ NAME ✨

__devlink_region_snapshot_create — create a new snapshot 🎀

This will add a new snapshot of a region. The snapshot will be stored on the region struct and can be accessed from devlink. This is useful for future analyses of snapshots 🔍✨ Multiple snapshots can be created on a region. The @snapshot_id should be obtained using the getter function — iykyk, don't just make one up 🙈

🦋 SYNOPSIS 🦋

int __devlink_region_snapshot_create (struct devlink_region *region , u8
*data , u32 snapshot_id );

🌈 ARGUMENTS 🌈

  • region — the devlink region of the snapshot 👑 this is your whole vibe, the thing you're snapshotting
  • data — the snapshot data 🍓 literally the actual contents
  • snapshot_id — the snapshot id to be created ⭐ this is the one you got from the getter function, no cap

💜 DESCRIPTION 💜

Must be called only while holding the region snapshot lock 🔒😤

fr fr, no negotiating on this one. Take the lock first, then call. That's the whole rule. Not me being dramatic, it's just the deal 💀
