devlink_region_create(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, we're in the Kernel API Manual today and the main character is devlink_region_create(9) — say that three times fast, i dare you 🫶

✨ NAME ✨

devlink_region_create — create a new address region 💖 lowkey doing exactly what it says on the tin, and honestly? iconic.

🎀 SYNOPSIS 🎀

struct devlink_region * devlink_region_create (struct devlink *devlink ,
       const struct devlink_region_ops *ops , u32 region_max_snapshots , u64
       region_size );

like, that's the whole signature, no cap. four args, one struct pointer coming back at you 🦋

🌸 ARGUMENTS 🌸

  • devlink — the devlink itself. yeah. that's the whole description. it's giving "trust me bro, you already know" 😭
  • ops — the region operations and the name, so this one's carrying the whole personality of your region fr fr 👑
  • region_max_snapshots — the maximum supported number of snapshots for the region. maximum. supported. number. so like, the ceiling, the limit, the "don't come for me beyond this" 💀
  • region_size — the size of the region. she's a u64, she contains multitudes ✨

🔥 CONTEXT 🔥

Takes and releases devlink->lock <mutex> — so yeah, she grabs the lock and puts it back, very responsible of her, we love a mutex-respecting queen 💅
