- * Once PV info has been populated in lvmcache and
- * lvmcache has chosen preferred duplicate devices,
- * set this flag so that lvmcache will not try to
- * compare and choose preferred duplicate devices
- * again (which may result in different preferred
- * devices.)  PV info can be populated in lvmcache
- * multiple times, each time causing lvmcache to
- * compare the duplicate devices, so we need to
- * record that the comparison/preferences have
- * already been done, so the preferrences from the
- * first time through are not changed.
- *
- * This is something of a hack to work around the
- * fact that the code isn't really designed to
- * handle duplicate PVs, and the fact that lvmetad
- * has its own way of picking a preferred duplicate
- * and lvmcache has another way based on having
- * more information than lvmetad does.
- *
- * If we come up with a better overall method to
- * handle duplicate PVs, then this can probably be
- * removed.
- *
- * FIXME: if we want to make lvmetad work with clvmd,
- * then this may need to be changed to set
- * preferred_duplicates back to 0.
