Mostly cited as evidence of the friction between kernel maintainers and Rust developers, notably in Wedson Almeida Filho's resignation.

> how considerate Ted Tso's writing always is This is less true when T'so asks questions at conferences, of course. [LINK] [VIDEO]

Its in a talk about File systems in Rust for Linux. Basically the rust maintainer who I think stepped down was talking about how the C-code base for VFS has a lot of documented but complex orderings where you have to call a lock, or pin before accessing an Inode(or something) one way but not the other. They made a bunch of Rust Types so you basically could not produce an illegal ordering and got heckled pretty hard by the "bearded guy". They basically run out the presentation time with heckling and I think the Rust maintainer quit a few months later (over many similar instances of this. don't quote me time line here) [source] [VIDEO]

> You can't go around screaming "your code SUCKS and you need to rewrite it my way NOW" It seems you are imagining things and hate people for the things you imagined. In reality there are situations where during technical discussions some people stand up and with trembling voice start derailing these technical discussions with "arguments" like "you are trying to convince everyone to switch over to the religion".
