We tend to either use indentations to the same level as the condition, or two tabs indents. But I also noticed that we shouldn't even need the cast here as fp already is unsigned long, so it should all fit on one line anyway: while (fp && !(fp & 0x3) && entry->nr < entry->max_stack) fp = user_backtrace(entry, fp, 0);
