    Unionfs: reduce number of whiteouts by deleting all instances of files
    
    Optimize the unlinking of non-dir objects in unionfs by deleting all
    possible lower inode objects from all writable lower branches.  This may
    consume a bit more processing, but on average reduces overall inode
    consumption and further saves a lot by reducing the total number of
    whiteouts needed.  We create a whiteout now only if we could not delete all
    lower objects, or if one of the lower branches was explicitly marked
    read-only.
