dma_resv_iter_begin(9)

✨ dma_resv_iter_begin(9) ✨

okay so bestie, welcome to the dma_resv_iter_begin(9) page from the Kernel API Manual 💖 this one's short and sweet but it's literally the glow-up moment for your iterator, so pay attention 🫶

---

🌸 NAME 🌸

dma_resv_iter_begin — initializes a dma_resv_iter object, no cap ✨

---

🎀 SYNOPSIS 🎀

void dma_resv_iter_begin (struct dma_resv_iter *cursor , struct dma_resv
*obj , enum dma_resv_usage usage );

it returns void, so like… don't @ me looking for a return value, there isn't one 💅

---

🦋 ARGUMENTS 🦋

• cursor — the dma_resv_iter object we're about to initialize. this is your main character, the one getting set up 💅
• obj — the dma_resv object we want to iterate over. this is the thing you're walking through, one fence at a time 🚶‍♀️
• usage — controls which fences get included in the iteration. it's an enum dma_resv_usage, so go check that enum if you need the deets, iykyk 👑

ngl there's not a lot of drama on this page — no warnings, no exit statuses, no environment variables. it's just "initialize the iterator," slay, iconic, go read the other pages for the spicy parts 🍓

k bye bestie, that's the whole page!! 🧚 this masterpiece lives in ./include/linux and it's dated October 2026 — mark your calendars, this is the version you're reading 💜👑
