[linux-lvm] unable to exclude LVs using global_filter

[Gordon Messmer]

I'd like to avoid scanning LVs, and I thought I'd set global_filter 
appropriately.  The following logs show global_filter set to reject 
^/dev/VolGroup/vm_, but the system is scanning 
/dev/VolGroup/vm_wiki_data.  Any hints as to what I'm doing wrong?
