ice_put_vf(9)

💅 ice_put_vf — the "release a reference to a VF" page, brought to you by the Kernel API Manual ✨

okay so bestie, if you're here it's because you grabbed a VF reference and now you gotta give it back. this is the giving it back page 🎀

---

🌸 NAME 🌸

ice_put_vf — release a reference to a VF, like returning a library book but the book is a virtual function and the librarian is the kernel 💀

---

⭐ SYNOPSIS ⭐

void ice_put_vf (struct ice_vf *vf );

---

🦋 ARGUMENTS 🦋

• vf — the VF structure to decrease reference count on. that's the one you're dropping a ref on, no cap 🫶

---

💖 DESCRIPTION 💖

so what this does is decrease the reference count for a VF, and free the entry if it is no longer in use. lowkey it's just the cleanup half of the whole get/put situation.

you must call this after ice_get_vf_by_id once the reference to the VF structure is no longer used. and like, i mean it bestie — otherwise, the VF structure will never be freed. not "eventually", not "when the vibes improve" — never. that's a memory leak with main character energy and you do NOT want it 🙈

so the rule is: if you got it with ice_get_vf_by_id, you put it back with ice_put_vf. pair them like matching nails 💅
