inlined from 'copy_name' at fs/hfsplus/xattr.c:416:3: ./include/linux/string.h:245:9: warning: '__builtin_strncpy' output truncated before terminating nul copying 4 bytes from a string of the same length [-Wstringop-truncation] Since we don't need to copy '\0', we can just use memcpy() to avoid this warning.
