I certainly asked whether you really need a real 'struct inode' for whiteouts, and suggested that they should be represented _purely_ as a dentry with type DT_WHT. I don't much like the manifestation of that in this patch though, especially with the made-up inode number. (ISTR I had other jffs2-specific objections too, which I'll dig out and forward). -- David Woodhouse Open Source Technology Centre David.Woodhouse@intel.com Intel Corporation
