Mikulas Patocka	550929faf8	dm persistent data: rename node to btree_node ... This patch fixes a compilation failure on sparc32 by renaming struct node. struct node is already defined in include/linux/node.h. On sparc32, it happens to be included through other dependencies and persistent-data doesn't compile because of conflicting declarations.
