dma_fence_is_later(9)

✨ dma_fence_is_later(9) ✨

okay bestie, we’re in the Kernel API Manual and this one is a tiny little boolean check with main-character energy 💅

---

🎀 NAME 🎀

dma_fence_is_later — return if f1 is chronologically later than f2 🕰️

---

🌸 SYNOPSIS 🌸

the whole signature, untouched, because we do not mess with code:

bool dma_fence_is_later (struct dma_fence *f1 , struct dma_fence *f2 );

---

🦋 ARGUMENTS 🦋

• f1 — the first fence from the same context 💫
• f2 — the second fence from the same context 💫

---

💖 DESCRIPTION 💖

Returns true if f1 is chronologically later than f2. Both fences must be from the same context, since a seqno is not re-used across contexts. no cap, that same-context detail is literally the whole vibe check 🔥
