I was going through the function "ext2_find_near" in inode.c and

ext2_find_near() explains a bit.
Colouring the location like that lessens the chances of a concurrent
allocation -- supposedly from a different PID -- finding the exact
same spot and both of them clashing at the point where the actual
allocation happens (so that, I suppose, one of them must go back and
try to find a new location all over again).
Now whether or "pid % 16" is actually a good colour in practice...
Rene.
Correct me if I'm wrong, but could the "pid % 16" be for page/block
alignment?
