    How to change vnode operation

    Hi all, this may sound a little odd, since I have noticed that there is much work done to not allow such a thing ($SUBJ). But may be you can help me and point me to the right direction. I am writing a kernel module with somewhat similar functionality like nullfs has, BUT it has to have...

    mount_nullfs not distinct paths
