so far, i've listed three areas that -- even after all these years -- still need care and feeding; they were: 1) replacing manual testing with the ARRAY_SIZE() macro 2) replacing "n & (n-1)" testing with "is_power_of_2(n)" call 3) simplifying Kconfig files by wrapping sections in if FUBAR ... lots of Kconfig stuff endif is that enough to keep people busy who want to do some janitor stuff? rday
