devlink_traps_unregister(9)

💅 devlink_traps_unregister — the kernel API manual, bestie edition 🎀

okay so real talk, this is a page from the Kernel API Manual and it's about devlink_traps_unregister(9). yes the whole title is the function name, we love a self-titled moment. let's get into it ✨

---

🌸 NAME 🌸

devlink_traps_unregister — Unregister packet traps from devlink.

like, it's the goodbye function. it takes your packet traps and politely removes them from devlink's whole thing. no cap 💅

---

✨ SYNOPSIS ✨

void devlink_traps_unregister (struct devlink *devlink , const struct
       devlink_trap *traps , size_t traps_count );

it returns void, so like… it gives you nothing back. not a single crumb. and honestly? that's fine, it's giving "I did the job, don't ask questions" energy 🫶

🦋 ARGUMENTS 🦋

• devlink — devlink. yes bestie that's the whole description, it's the devlink pointer, she's the main character and she knows it 👑
• traps — Packet traps. this is the pointer to your traps, plural, the whole squad 🎀
• traps_count — Count of provided packet traps. literally just how many traps you're handing over — a size_t, so, you know, don't be weird about it 🙈

---

🔥 CONTEXT 🔥

Takes and release devlink->lock <mutex>.

so it grabs the mutex and then lets it go. in and out. a little lock-and-release moment. do NOT forget that this is happening, because the lock is not decorative, it's iconic and it's real ⭐

🌈 SEE ALSO 🌈

Kernel file ./net/devlink/trap.c — go read the source, it's giving lore:

• struct devlink_trap_policer_item(9)
• struct devlink_trap_group_item(9)
• struct devlink_trap_item(9)
• devl_traps_register(9)
• devlink_traps_register(9)
• devl_traps_unregister(9)
• devlink_trap_report(9)
• devlink_trap_ctx_priv(9)
• devl_trap_groups_register(9)
• devlink_trap_groups_register(9)
• devl_trap_groups_unregister(9)
• devlink_trap_groups_unregister(9)
• devl_trap_policers_register(9)
• devl_trap_policers_unregister(9)

like I said, the whole friend group. register versions, unregister versions, the devl_ variants, the trap/group/policer branches — it's a whole ensemble cast and they all ate 🔥💀

---

ngl the only actual gotcha here is that mutex. devlink->lock gets taken and released for you. you don't do it yourself, it just happens. that's the whole vibe check 🧚
