Tabs are there so that the user can set their width according to _their_ taste, simply so that both sides, from CodingStyle: Tabs are 8 characters, and thus indentations are also 8 characters. There are heretic movements that try to make indentations 4 (or even 2!) characters deep, and that is akin to trying to define the value of PI to be 3. Linus (did he wrote that part?) and the heretics both can have their fun without impacting each other. If we wanted to force the user to have exactly 8 screen blanks, we should use spaces throughout. (And BTW, int pi = 3.141592 _is_ going to be 3 ;-) and floating point is mostly an agreed no-go in kernel anyway, even if it's supported.)
