devlink_regi...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. It's giving "create a new snapshot" energy, and honestly? Iconic.

✨ 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 literally useful for future analyses of snapshots, no cap. Multiple snapshots can be created on a region — yes bestie, more than one, we stan a region with range 🫶. The @snapshot_id should be obtained using the getter function. don't just make one up, i'm begging 🙈

🌈 SYNOPSIS 🌈

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

one function, three args, zero drama. periodt.

🎀 ARGUMENTS 🎀

  • region — devlink region of the snapshot. it's the vibe check of where this snapshot lives 💅
  • data — snapshot data. the actual content, the moment, the memories 😭
  • snapshot_id — snapshot id to be created. the little name tag so everyone knows who's who 🏷️
real talk though: that snapshot_id has got to be the one you got from the getter function. no bootlegging ids, bestie — that's not the flex you think it is 🔥
