By putting such + headers into there, the relevant kernel code is easier to understand, + because the user will expect that the file named <alloca.h> or + <sys/types.h> does more or less what the normal C library file does, and + calling those <kern/alloca.h> or <kern/types.h> would make the reader have + to wonder or remember what they are. The directory is, essentially, a + special `/usr/include' for use by the kernel itself when compiling. It + only should get things which belong in `/usr/include'. The reason for + <alloca.h> and <sys/types.h> is because those are files found in + `/usr/include', even if on an actual installed system the versions in + `/usr/include' are provided by a different package. |
