title: A FUSE like file system
body: <p>I need to develop my own file-system. The thing is that I only need a specific behavior in a few callbacks (such as read, write, open etc.) and I don't want to wast time on dealing with Inodes and creating a new FS from scratch.</p>
  
  <p>I have once stumbled upon FUSE (file-system in user space), and that is almost every thing I need, except FUSE has over head (copy to and from user) because it is in user space.</p>
  
  <p>Is there something like FUSE, but in kernel space? or is there a way to avoid the copy_to and copy_from?</p>
  
  <p>Thanks,</p>
