Hello all: In arch x86 directory I found two global variables with the same name(master branch): 1.arch/x86/boot/main.c near line 18: struct boot_params boot_params __attribute__((aligned(16))); 2.arch/x86/kernel/setup.c near line 75: struct boot_params boot_params; Is that wrong to define two global variables with the same name? And when use extern to reference the variable,which one did it reference?
