Bryn M. Reeves	00ed523659	libdm: add dm_stats_get_{current_}area_offset() ... Add a method to retrieve the offset of an area within the containing region (rather than the offset within the containing device returned by dm_stats_get_area_start()). Although users of the library can calculate this themselves it is better to provide this through a method call to avoid users making assumptions about the structure of regions and areas.	2015-08-14 22:03:37 +01:00
Alasdair G Kergon	043fb32c4b	dmsetup: Restructure arg handling. ... Introduce enums and global variables to record cleanly which command we are processing and eliminate the historically inconsistent use of the shifted argv[0] and fix assorted bugs discovered along the way. Add dm_report_is_empty() to indicate there is no data awaiting output and use this to suppress dmsetup report headings when no data is output so we don't get a stray line saying 'Help' at the end of reporting help. Define a report type (as the interface requires) so -o all selects the right fields in splitname. (A fix for stats list will follow.) Exit immediately if no device is supplied to dmsetup wipe_table instead of hitting errors later and failing. Adjust the command name printed in usage/help output to match command invoked (most of the time).	2015-08-13 22:30:39 +01:00
