Hi.. > I'm reading the mm code now in linux2.4, I found the codes reads > difficultly, do you think it is a good beginning that read the 2.4 > kernel? try to start with oomkill.c, it is suggested (by Rik himself) as the easiest part to be studied :) IMHO, reading 2.4.x codes is still worth to do. Even later you'll find out the facts is no longer correct in 2.6.x, you still got the big picture since usually the "design" is still similar. So, make up your mind, pick certain version and dig into it. You'll get the true Penguin Power later :)) regards, Mulyadi -- Kernelnewbies: Help each other learn about the Linux kernel.
