The moti= vation is sound =E2=80=94 avoiding wasted host memory for BOs that are neve= r CPU-mapped. However, the patch has several issues ranging from a potential **indefinite= hang** (the error path in deferred mapping), to missing UAPI input validat= ion, to unhandled dma-buf export paths. These need to be addressed before m= erging. --- --- Generated by Claude Code Patch Reviewer
