The function uses pos to find the appropriate page and writes data there. Anyway, if marking buffers dirty works for you, go for it. However, what are you going to do if the part of the file you are intereste in is not cached in memory yet? Good luck, Martin Jambor -- Kernelnewbies: Help each other learn about the Linux kernel.
