vmw_resource..._reservation(9)

💅 NAME 💅

vmw_resource_backoff_reservation — the lil cleanup queen that unreserves and unreferences a guest memory buffer. literally just undoing the reservation and dropping the reference, no cap ✨

this one lives in the Kernel API Manual bestie, so buckle up 🎀

---

✨ SYNOPSIS ✨

void vmw_resource_backoff_reservation (struct ww_acquire_ctx *ticket ,
struct ttm_validate_buffer *val_buf );

okay so it's void, it takes two things, and it does the backoff. that's the whole vibe 🦋

---

🌸 ARGUMENTS 🌸

• ticket — the ww acquire ctx that was used for the reservation. yes, that ticket. the one you used to get in 🎟️
• val_buf — guest memory buffer info. the buffer in question, all dressed up with its info 🫶
