💅 devl_trap_policers_register 💅

okay so bestie, welcome to the devl_trap_policers_register(9) page — yeah, it's a kernel API manual, section 9, and it's literally about registering packet trap policers with devlink. iykyk. let's get into it 🎀

---

✨ NAME ✨

devl_trap_policers_register — register packet trap policers with devlink. that's it, that's the whole vibe. no cap. 🦋

---

✨ SYNOPSIS ✨

int devl_trap_policers_register (struct devlink *devlink , const struct
       devlink_trap_policer *policers , size_t policers_count );

like, look at her. she's giving "i take three arguments and i return an int". main character energy fr fr 🔥

---

✨ ARGUMENTS ✨

• devlink — the devlink. yes, that's the whole description, and honestly? iconic. it's the devlink you're working with, periodt.
• policers — packet trap policers. the actual policers, the const struct devlink_trap_policer squad. 🫶
• policers_count — count of provided packet trap policers. like, how many of them you just handed over, as a size_t. no guessing, bestie, you tell it exactly how many. 💅

---

✨ RETURN ✨

non-zero value on failure. 😭 so yeah — if it comes back non-zero, something went sideways. zero? she ate. 👑

lowkey important: the docs only promise non-zero on failure — don't go assuming any specific non-zero number means anything special, okay? 🙈
