If you have actualy read the structure, you would have known, that it contains a generic pointer field (called private_data, which, I hope, is clear enough). Just abuse it for anything you want. As for adding fields to structs, are you actualy sure, that all code, and especialy the code setting up the kmem_caches, used the same definition of the struct? ------------------------------------------------------------------------------- Jan 'Bulb' Hudec <bulb@xxxxxx>
