It's a great question. I mean, my read of it is he hates the idea of Rust4Linux and is using his position to obstruct.

Apparently not.

The patch he rejected did not add any code to C DMA, nor C DMA's directory (kernel/dma). Just:

  rust/bindings/bindings_helper.h |   1 +
  rust/kernel/dma.rs              | 271 ++++++++++++++++++++++++++++++++
  rust/kernel/lib.rs              |   1 +

(Nor does any Rust4Linux code add any maintenance burden to C -- C maintainers are allowed to break Rust code at will.)
