✨ NAME ✨

ttm_eu_backoff_reservation — yes that's the whole name, the original authors left the description blank, no cap, we're working with what we've got 🫶

---

✨ SYNOPSIS ✨

void ttm_eu_backoff_reservation (struct ww_acquire_ctx *ticket , struct
list_head *list );

look at that signature, it's giving very much "i take two things and i return nothing" 💅

---

✨ ARGUMENTS ✨

• ticket — a ww_acquire_ctx from the reserve call 👑 like, the little receipt you got when you reserved stuff.
• list — the thread private list of ttm_validate_buffer structs. yes, thread private, that's the vibe, don't share it with other threads bestie 🙈

---

✨ DESCRIPTION ✨

so what does it do?? it undoes all the buffer validation reservations for the bos that the list entries point to. literally the "jk, never mind" of kernel functions 😭 it backs off, it releases, it lets those bos go. iconic behaviour fr fr ✨
