This function behaves a little bit different than vg_reduce_single, because it allowes to remove even the latest pv. This has been done to be consistent to lvm_vg_create, which creates an empty vg. removed_pvs has been added to the volume_group struct. vg_reduce adds remove pvs to this list to be able to commit the changes for the pvs in lvm_vg_comm in liblvm2app. Initialize removed_pvs list in format-specific volume_group constructors. Ideally, we should have a base constructor here that initializes the general non-format specific members of struct volume_group. But until then, there are multiple places to initialize these members. Maybe a better patch would be a base constructor patch for struct volume_group. That is more work though.
