My favorite gems from the stuff even checkpatch finds in the 
INFINIBAND_NES driver, for which Linus has stated explicitely that 
merging it in this state in 2.6.25 was correct, can be seen with

  grep -C4 volatile drivers/infiniband/hw/nes/nes_nic.c


When we have the resources to maintain this kind of code, how could a 
small filesystem be a problem?
