this one is easy to fix btw; I wrote a small tool a while ago (and
posted to the list) to sort the file in disk order
OK, fine, but I can't find it. Could you repost it?
And would you be interested in a kernel module that tracks the read
files during boot? Or do you find that useless? And you as a great
kernel hacker :-) , what would you use? LSM? KProbes? Else?
