[linux-lvm] WARNING: Ignoring duplicate config node: filter (seeking filter)

[Cisco]

 Hi all,
 
 after upgrading (compiling from source)LVM2 and device 
 mapper, i always get the warning message "WARNING: Ignoring 
 duplicate config node: filter (seeking filter)" when doing 
 "lvm version" or any other lvm command.
 
 Does anyone know what's going on and if i should be 
 concerned about this, or even better: What is the meaning of 
 this message and how can i get rid of it.
 
 Thanks in advance and best regards.
