@Clemens newbie question : About the filesystem, what hook is used when node contents need to be read? If i want some functionality on the read operation, I should implement the fs_vnode_ops::read right? i.e. I need to define the interface for VFS so that VFS knows what to do when it wants to read data from a file. I had thought earlier that VFS read would simple read from a node in my filesystem and any custom functionality would be implemented in my implementation of node. I was looking for a node object with a data property but i couldn't find it
