Has the kmalloc problem in Reiserfs gone away? It used to be that the limit for a Reiser filesystem was determined by how many pointers could fit into a kmalloced chunk of memory; thus the 64-bit system limit was half teh 32-bit system limit. -- Dr Peter Chubb http://www.gelato.unsw.edu.au peterc AT gelato.unsw.edu.au The technical we do immediately, the political takes *forever*
