lvm2/lib/filters/filter-persistent.h
Milan Broz 9ad39e546b Currently if clvmd is running and user issues vgscan,
the device cache file is dumped both in vgscan and clvmd process.

Unfortunately, clvmd calls lvmcache_label_scan,
it properly destroys persistent filter, but during
persistent_filter_dump it merges old cache content back!

This causes that change in filters is not properly propagated
into device cache after vgscan on cluster.
(Only new devices are added.)
