💫 fc_exch_ptr_set — the Kernel API Manual has entered the chat

okay so bestie, welcome to fc_exch_ptr_set, live from the Kernel API Manual ✨ this one's short and sweet and honestly it's giving "tiny function, huge responsibility" energy. Let's get into it 🎀

---

✨ NAME ✨

fc_exch_ptr_set — assign an exchange to a slot in an exchange pool 🌸

like, you've got a pool and you've got an exchange and the vibes are not yet connected. this function fixes that. matchmaker behavior fr fr 💅

---

🦋 SYNOPSIS 🦋

void fc_exch_ptr_set (struct fc_exch_pool *pool , u16 index , struct
fc_exch *ep );

that's it. that's the whole signature. no return value, no drama, she just does the thing and dips 🔥

---

💖 ARGUMENTS 💖

• pool — the pool you're assigning the exchange to 🫶 it's the group chat the exchange is about to be added to, no cap
• index — the index in the pool where the exchange will be assigned ⭐ like, which exact seat bestie is sitting in
• ep — the exchange to assign to the pool 💜 the main character of this whole operation, deservedly so

ngl bestie, that's a lot of cross-references for a function that just puts a pointer in a slot — but that's libfc for you, iconic and interconnected 💀

and that's the whole page fr fr 🍓 so much love to ./drivers/scsi/libfc, dated October 2026, for bringing us this absolute gem. go set some pointers, bestie, you've got this 💅✨🌈
