It causes build failures with unusual CC/HOSTCC combinations. Quoting https://lkml.kernel.org/r/A222B1E6-69B8-4085-AD1B-27BDB72CA971@goldelico.com: HOSTCC scripts/mod/modpost.o - due to target missing In file included from include/linux/string.h:5, from scripts/mod/../../include/linux/license.h:5, from scripts/mod/modpost.c:24: include/linux/compiler.h:246:10: fatal error: asm/rwonce.h: No such file or directory 246 | #include <asm/rwonce.h> | ^~~~~~~~~~~~~~ compilation terminated. ... The problem is that HOSTCC is not necessarily the same compiler or even architecture as CC and pulling in <linux/compiler.h> or <asm/rwonce.h> files indirectly isn't a good idea then. My toolchain is providing HOSTCC = gcc (MacPorts) and CC = arm-linux-gnueabihf (built from gcc source) and all running on Darwin. If I change the include to <string.h> I can then "HOSTCC scripts/mod/modpost.c" but then it fails for "CC kernel/module/main.c" not finding <string.h>: CC kernel/module/main.o - due to target missing In file included from kernel/module/main.c:43:0: ./include/linux/license.h:5:20: fatal error: string.h: No such file or directory #include <string.h> ^ compilation terminated.
