И там же:
Раст "это одна из тех вещей, на которые уйдут годы прежде, чем она станет важной частью ядра, но она определённо станет одной из них". Т.е. уже свершившийся факт.

Вообще смысл таскать куски, лучше сразу привести все.

It's been growing, but we don't have any part of the kernel that really depends on Rust yet. To me, Rust was one of those things that made technical sense, but to me personally, even more important was that we need to not stagnate as a kernel and as developers.

Rust has not really shown itself as the next great big thing. But I think during next year, we'll actually be starting to integrate drivers and some even major subsystems that are starting to use it actively. So it's one of those things that is going to take years before it's a big part of the kernel. But it's certainly shaping up to be one of those.
