Hey, if we have 50 million machines running 2.6 for three years, this optimization saves 100 clock cycles per boot (most kstrdups are device init), and machines boot once a month, and average 1GHz, that's three minutes of saved time. I think Jeff and I should start the kstrdup sourceforge project immediately...
