[PATCH 0/5] hybrid union filesystem prototype

From: Miklos Szeredi
Date: Thu Aug 26 2010 - 14:35:21 EST


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
