Pass the single vgname as a new process_each_vg arg instead of setting a cmd flag to tell process_each_vg to take only the first vgname arg from argv. Other commands with different argv formats will be able to use it this way.

|
* The "struct processing_handle" is used as a handle for processing
|
|
* functions (process_each_* and related).
|
|
*
|
|
* The "custom_handle" is any handle used to pass custom data into
|
|
* process_each_* and related functions.
|
|
*
|
|
* The "internal_report_for_select=0" makes processing function to
|
|
* skip checking the report/selection criteria (if given on cmd line)
|
|
* before executing the action on the item.
|
|
*
|
|
* The "selection_handle" is only used if "internal_report_for_select=1".
|
|
*
|
|
* Some important notes about selection:
|
|
* =====================================
|
|
* In case we're processing for display, the selection is directly
|
|
* a part of reporting for the display on output so we don't need to
|
|
* report the item in memory to get the selection result, then dropping
|
|
* the report and then reporting the same thing again for it to be
|
|
* displayed on output.
|
|
* For example, compare these code paths:
|
|
*
|
|
* - when reporting for display on output:
|
|
* _report -> process_each_* -> ... -> dm_report_object
|
|
* (Here the dm_report_object does both selection and
|
|
* reporting for display on output.)
|
|
*
|
|
* - for any other processing and reporting for selection:
|
|
* process_each_* -> _select_match_* -> ... -> dm_report_object_is_selected
|
|
* |
|
|
* --> (selection result) --> ...
|
|
* (Here the dm_report_object_is_selected just gets
|
|
* the selection result and it drops reporting buffer
|
|
* immediately. Then based on the selection result,
|
|
* the process_each_* action on the item is executed
|
|
* or not...)
|
|
*
|
|
* Simply, we want to avoid this double reporting when reporting
|
|
* for display on output:
|
|
* _report -> process_each_* -> _select_match_* -> ... -> dm_report_object_is_selected
|
|
* |
|
|
* --> (selection result) -> dm_report_object
|
|
*
|
|
* So whenever the processing action is "to display item on output", use
|
|
* "internal_report_for_select=0" as report/selection is already
|
|
* a part of that reporting for display (dm_report_object).
