Split out the partitioned device filter that needs to open the device and move the multipath filter in front of it. When a device is multipathed, sending I/O to the underlying paths may cause problems, the most obvious being I/O errors visible to lvm if a path is down. Revert the incorrect <backtrace> messages added when a device doesn't pass a filter. Log each filter initialisation to show sequence. Avoid duplicate 'Using $device' debug messages.
