✨ NAME ✨

amdgpu_sync_keep_later — keep the later fence 🕐🫶

like, literally, that's the whole job. she looks at two fences and keeps whichever one is later. no cap.

🦋 DESCRIPTION 🦋

okay so here's the vibe check: you've got two fences, and the function is gonna either keep the existing fence or the new one — depending on which one is later. that's it. that's the whole plot. 🎬
