Funny! :) However, in reality Linus wont necessarily review the patch line by line. Mostly the reviews will happen on mailing lists. Then if Linus' lieutenants that handle the specific subsystem like what they see, they will probably give a general thumbs up for the change. Finally Linus will take an executive call. He may offer some technical suggestions (as he is technical) and send it back or accept the patch or conditionally accept the patch. The point is that the finer details will have already been dealt with by the time it lands on Linus' desktop. But given that this is going to affect a lot of things for years to come he is probably going to spend a lot more time on it than other features. Also I think Linux may be interested in having Rust in the kernel. See here https://lkml.org/lkml/2021/4/14/1099 https://lkml.org/lkml/2021/4/14/1099 . He says "on the whole I don't hate it". It's clear to see that there is a lot of momentum behind Rust. Allowing Rust in the Linux kernel will help bring a lot more talent and energy into the kernel community (other than the inherent merits of Rust which I think are easy to see).
