Description Jonathan Earl Brassow 2006-05-16 10:11:08 EDT
device-mapper/lib/libdm-deptree.c:_emit_segment_line() improperly handles the
counting of parameters - causing an inability to create single machine mirrors
with core logs.

This is essential to the correct operation of LVM2 mirroring, because LVM2 relys
on being able to create mirrors with core logs in order to cope with the failure
of the disk log device.
