- add copyright notice for 10-dm.rules.in,
- set DM_UDEV_DISABLE_{DISK, OTHER}_RULES_FLAG in 11-dm-lvm.rules directly
for inappropriate and non-top-level subdevices in case we use older kernels
where DM_COOKIE is not used (and therefore there are no flags passed from
the LVM process itself). This applies for older kernels (version < 2.6.31),
- remove unnecessary filters in 95-dm-notify.rules - the DM_COOKIE env var
itself is set for change/remove udev events and for DM devices only so
there's no need to double-check this.
