There's a better solution - just make simple_lookup() skip d_set_d_op() if superblock already has ->s_d_op (and thus d_alloc() has already set the damn thing). Voila - we can just set ->s_d_op and leave inode_operations as is. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
