By saying that Hector is the problem, he’s implicitly saying that Christoph is not the problem. By saying that the current process works–the very same process that just prevented R4L from submitting patches to the kernel, he’s implicitly endorsing Christoph’s actions.
The boiled down summary is:
Abdiel Janulgue submits the patch to Christoph Hellwig
Christoph rejects the patch because he doesn’t want to maintain it
Danilo Krummrich offers to maintain it
Christoph says no and that he “will do everything [he] can do to stop [Rust support from being added to the DMA subsystem]”
Hector Martin adds Linus and says “If Linus doesn’t pipe up with an authoritative answer to this thread, Miguel and the other Rust folks should just merge this series once it is reviewed and ready, ignoring Christoph’s overt attempt at sabotaging the project.”
Linus says “How about you accept the fact that maybe the problem is you. You think you know better. But the current process works.”
