It is in https://lore.kernel.org/lkml/20210704202756.29107-11-ojeda@xxxxxxxxxx/#Z30rust:kernel:print.rs Yeah, perhaps it would have been better to put it in the `kernel` crate commit alongside `include/linux/spinlock.h` and `kernel/printk/printk.c`. On the other hand, having C changes on other commits may be easier to read and explain (note that compilation still works, given things are only enabled near the end in the Kbuild commit).
