This is v12 of the Rust bindings for GEM shmem, adding SGTable and VMap support on top of the existing shmem bindings. The series is well-structured: two C-side preparatory patches (extracting `__drm_gem_shmem_free_sgt_locked` and exporting `drm_gem_shmem_get_pages_sgt_locked`), followed by three Rust patches building SGTable and VMap abstractions.
The overall design is sound — using `Devres` to ensure SGTable mappings are revoked on driver unbind is the right approach for safety. The VMap abstraction with borrowed vs. owned variants and integration with the `Io` trait is clean.
There are a few concerns worth discussing, primarily around locking patterns in the Rust code (non-interruptible `dma_resv_lock` calls, lock not released on error paths), a naming mismatch in the C-side kdoc, and some safety reasoning that could be tightened. Nothing is a showstopper, but a couple of items warrant attention before merging.
