Maybe because it's #define elfhdr elf64_hdr. > fs//proc/kcore.c:368:23: sparse: expression using sizeof(void) > fs//proc/kcore.c:368:23: sparse: expression using sizeof(void) > >> fs//proc/kcore.c:384:49: sparse: missing braces around initializer This is > > 384 struct elf_prstatus prstatus = {0}; GCC doesn't complain, but I guess I can change it to "= {};", which isn't strict C89 but both GCC and sparse are happy with.
