Re: Bad timing?
"I think he quite likes the idea of Rusty modules."
Not really. He use words like "we might" and "maybe we will" and "perhaps rust" and "eventually", and "drivers, probably" etc. etc. Nowhere does he say "Let's do it" or "We are going to" or "It will be soon".
He also is on record as saying ""I don't think Rust will take over the core kernel, but doing individual drivers (and maybe whole driver subsystems) in it doesn't sound entirely unlikely." ... but again, he's not entirely enthusiastic. He has also said "It might not be rust", which to me is a death knell.
I;ve been reading the LKML for as long as it;s been around, and from my perspective it looks like Linus isn't really interested in any language that isn't C for kernel use ... not C++, just good old C ... and seeing as Rust is a replacement for C++, not C ,,, well, do the math.
I think he's throwing the yowling, baying fanbois a bone just to shut them up. We might get a few drivers & the like written in rust over the next few years, but the vast majority of the kernel will still be in C long after the next language du jour takes the place of rust in the fanboi's fancy.
