That's an idea I thought of as well, but wanted to start small, since I really am new to C programming. Now that I've done this part, I'll look at the various vop_* pieces and see if it's something in my grasp. From what it sounds like, you'd also like to see per-mount point stats, but from the vfs layer, right? If that's true, then do you have any suggestions on how to store the statistics for each mounted fs? Thanks for the feedback!
