netlbl_calipso_remove_cb(9)

💅 netlbl_calipso_remove_cb — a kernel API manual, but make it make sense

okay so bestie, welcome to netlbl_calipso_remove_cb(9) from the Kernel API Manual — yes we're in kernel land today, grab a lil snack, it's gonna slay 🍓

---

✨ NAME ✨

netlbl_calipso_remove_cb — the netlbl_calipso_remove() callback for REMOVE 🧹

like, this is the little function that gets called when the removing happens. it's giving cleanup crew energy and honestly? iconic.

---

🦋 SYNOPSIS 🦋

int netlbl_calipso_remove_cb (struct netlbl_dom_map *entry , void *arg
);

look at her. two args, one int return. short, sweet, does her job. no cap 💅

---

🌸 ARGUMENTS 🌸

• entry — the LSM domain mapping entry. hi bestie, you're on the list (and possibly about to be off the list 👀)
• arg — the netlbl_domhsh_walk_arg structure. the lil carry-on bag of context that gets passed along the walk 🎀

---

💖 DESCRIPTION 💖

so the way this works: this function is intended for use by netlbl_calipso_remove as the callback for the netlbl_domhsh_walk function. iykyk.

what it does is remove LSM domain map entries that are associated with the CALIPSO DOI specified in arg. that's the whole vibe — walk in, find the ones tied to that specific CALIPSO DOI, yeet them out. 🔥

and for the return value, keep this in your notes app:

• returns zero on success ✅
• returns negative values on failure 😭

periodt. no mystery, no drama, that's the contract.
