Sure, we have to implement whiteouts to support overlayfs.
Though internally we'll do it with DT_WHT in dirents, so we don't
need inodes on disk for them. lookups will just have to allocate in
memory chardev inodes so the rest of the world will function
appropriately if they access whiteouts from the lower filesystems.
Cheers,
Dave.
