dsa_lag_unmap(9)

💅 dsa_lag_unmap — from the Kernel API Manual, section 9, bestie

okay so picture this: you're deep in the kernel, section 9 of the manual, and you need to unmap a LAG ID. that's the whole vibe. dsa_lag_unmap is the function that does the un-mapping, and honestly? she's a team player about it. 🎀

---

✨ SYNOPSIS ✨

void dsa_lag_unmap (struct dsa_switch_tree *dst , struct dsa_lag *lag );

no return value, no drama — it's void, she just does the thing and dips. 🦋

---

🌸 ARGUMENTS 🌸

• dst — the tree 🌳 where the mapping is recorded. like, the official record-holder. that's where the paperwork lives.
• lag — the struct dsa_lag that was mapped. the one getting un-mapped. her moment. 👑

---

💖 DESCRIPTION 💖

so here's the tea, and it's genuinely important: there might be multiple users of that mapping. like, several besties sharing the same locker. so dsa_lag_unmap does not just yank it — it only removes the mapping if there are no other references to it. 🫶

no cap, that's the whole rule. reference count hits zero? mapping's gone. somebody else still holding on? it stays. respect the refcount, periodt. 💅

lowkey the most responsible function in the file and i'm obsessed with her for it ✨
