This is a well-structured 5-patch series by Alice Ryhl (with co-development from Asahi Lina and Daniel Almeida) providing Rust bindings for the DRM GPUVM subsystem in immediate mode. The series introduces safe Rust wrappers around the C `drm_gpuvm`, `drm_gpuvm_bo`, and `drm_gpuva` types, along with split/merge (sm) map/unmap operations.
The overall design is sound: the `UniqueRefGpuVm` pattern enforces exclusive access to the interval tree and mutable driver data, the invariant lifetime trick on `OpMap`/`OpUnmap`/`OpRemap` ensures drivers can't return a completion token from the wrong operation, and the type-state pattern (`GpuVaAlloc` -> inserted `GpuVa` -> `GpuVaRemoved`) encodes the VA lifecycle at the type level.
The series is at v6, has Reviewed-by tags from Daniel Almeida, and the incremental changes show careful iteration on locking, Send/Sync bounds, and the extobj race condition fix. I found a few issues worth flagging, ranging from a potential bug in error handling to minor documentation nits.
