[$] FFI type mismatches in Rust for Linux

Fri, 11 Oct 2024 13:56:48 +0000

Description:
At Kangrejos, Gary Guo wanted to discuss three problems with the way
Rust and C code in the kernel interact: mismatched types, too many type casts,
and the overhead of helper functions. To fix the first two problems, Guo 
proposed
changing the way the kernel maps C types into Rust types. The last problem 
was a
bit trickier, but he has a clever workaround for that, based on tricking
the compiler into inlining the helper functions across language boundaries.
