Subject: [PATCH 0/5] hybrid union filesystem prototype

This is the result of my experimentation with trying to do
union-mounts like semantics with a filesystem.  The implementation is
far from perfect, but I think the concept does sort of work.  See the
patch header for the union filesystem.

VFS modifications necessary to make it work:

  - allow f_op->open() to return a different file
  - pass dentry to i_op->permission() instead of inode
  - hack to vfs_rename() to allow rename to same inode

Git tree is here:

Thanks,
Miklos
