linux-headers@5.15 for Mac

linux-headers@5.15 provides the header files corresponding to Linux kernel version 5.15, intended primarily for compiling kernel modules or programs that need to interact with kernel interfaces. It is not a command that is run directly in daily use, but rather a foundational component of the development and build process: for example, when installing certain drivers, compiling external modules, or building software that depends on kernel interfaces, the system is often required to have matching header files present. It is suitable for developers and system maintainers who need to compile kernel-related code on the local machine; ordinary users generally do not need to pay attention to it separately.
