Specifically, I was going to take VFS_MOUNT() and change path to be a kernel string rather than a user string. I was then going to modify all the filesystem code to DTRT. Then, I was going to wrap mount() into domount(), much like unmount() and doumount() function. The next part of the change involves doing the same thing to flags and data, which is going to be a little tricker and require a hell of a lot more work. Does anyone have any problems with this?
