The new check_single_lv() function is called prior to the existing process_single_lv(). If the check function returns 0, the LV will not be processed. The check_single_lv function is meant to be a standard method to validate the combination of specific command + specific LV, and decide if the combination is allowed. The check_single function can be used by anything that calls process_each_lv. As commands are migrated to take advantage of command definitions, each command definition gets its own entry point which calls process_each for itself, passing a pair of check_single/process_single functions which can be specific to the narrowly defined command def.
