o Filter which caches valid devices in a file. Pass in init == 1 to the constructor if you want it to ignore the existing cache and check every device again (eg, vgscan, pvscan).

#ifndef _LVM_FILTER_PERSISTENT_H
o composite filter that allows us to merge filters. Think of it as &&'ing filters in order. eg, f = composite_filter_create(2, regex_filter, persistent_filter); ownership of the filters passes, they will be destroyed when f's destroy method is called.

#include "dev-cache.h"
refactor: make device type recognition code common for general use Changes: - move device type registration out of "type filter" (filter.c) to a separate and new dev-type.[ch] for common use throughout the code - the structure for keeping the major numbers detected for available device types and available partitioning available is stored in "dev_types" structure now - move common partitioning detection code to dev-type.[ch] as well together with other device-related functions bound to dev_types (see dev-type.h for the interface) The dev-type interface contains all common functions used to detect subsystems/device types, signature/superblock recognition code, type-specific device properties and other common device properties (bound to dev_types), including partitioning support. - add dev_types instance to cmd context as cmd->dev_types for common use - use cmd->dev_types throughout as a central point for providing information about device types

const char *file);
Move the core of the lib/config/config.c functionality into libdevmapper, leaving behind the LVM-specific parts of the code (convenience wrappers that handle `struct device` and `struct cmd_context`, basically). A number of functions have been renamed (in addition to getting a dm_ prefix) -- namely, all of the config interface now has a dm_config_ prefix.
