kernel: separate headers into kernel and user headers all kernel headers have been moved from include/mango to include/kernel and include definitions that are only relevant to kernel-space. any definitions that are relevant to both kernel- and user-space (i.e. type definitions, syscall IDs) have been moved to include/mango within libmango. 2026-02-19 18:54:48 +00:00			`#include <kernel/libc/string.h>`
