*ring , struct amdgpu_job *job , struct amdgpu_vmid **id );

literally the whole signature, copied exactly, because we do NOT play with code around here ✨

🦋 ARGUMENTS 🦋

• vm — the vm we're allocating an id for. bestie's home base 💖

🌈 DESCRIPTION 🌈

Try to reuse a VMID for this submission. that's it, that's the whole vibe — it's a try, ngl, not a guarantee, so don't come for me if it doesn't land 🙈 lowkey the whole point is recycling a VMID instead of grabbing a fresh one for this submission. recycle era ♻️✨
