libdm: add dm_bitset_parse_list() Add a function to parse a list of integer values and ranges into a dm_bitset representation. Individual values signify that that bit is set in the resulting mask and ranges are given as a pair of start and end values, M-N, such that M and N are the first and last members of the range (inclusive). The implementation is based on the kernel's __bitmap_parselist() that is used for cpumasks and other set configuration passed in string form from user space.

dm_bitset_parse_list
libdm: add statistics groups Add a grouping facility to the libdm-stats library that allows the user to bind several regions together as a group. Groups may be used to aggregate data from several regions for reporting, or to select and sort among large sets of regions. A textual descriptor ("group tag") is associated with each group and is stored in the first group member's aux_data field. The tag contains the group member list and an optional alias for the group, allowing the user to assign meaningful names to groups of regions. These descriptors are parsed in @stats_list message responses and populate the resulting region and area tables with the group structure. Groups with overlapping regions are permitted but since this will result in some events being counted more than once a warning is printed in this case. Nested and overlapping groups are not currently supported and attempting to create these configurations results in error.

dm_stats_create_group
libdm: add stats group and region iterators and properties Add support do dm_stats_walk*() to walk over the set of available groups using the cursor embedded in the dm_stats handle, and to obtain the type of the object at the current stats cursor location. A set of flags is introduced to control which objects are visited: DM_STATS_WALK_AREA DM_STATS_WALK_REGION DM_STATS_WALK_GROUP DM_STATS_WALK_ALL A final flag suppresses visits to regions that contain only a single area - since the aggregate of such a region is idential to the area it contains this allows these duplicates to be filtered out: DM_STATS_WALK_SKIP_SINGLE_AREA If flags are not initialised before beginning a walk the default set matches the behaviour of previous versions of the library. Also accept group identifiers as immediate arguments to the counter, metric, and property functions by adding control flags to the region and area identifiers passed in. Region and area properties are mapped to their equivalents for the group (for example: group size is reported as the sum of all regions contained in the group). Counter and metric values are aggregated for the region or group.

dm_stats_delete_group
dm_stats_get_alias
libdm: add enum based counter and metric calls Add a new enum based interface for accessing counter and metric values that uses a single function for each: uint64_t dm_stats_get_counter(const struct dm_stats *dms, dm_stats_counter_t counter uint64_t region_id, uint64_t area_id); int dm_stats_get_metric(const struct dm_stats *dms, int metric, uint64_t region_id, uint64_t area_id, double *value); This simplifies the implementation of value aggregation for groups of regions. The named function interface now calls the enum interface internally so that all new functionality is available regardless of the method used to retrieve values.
