This fixes 670bf3e8 which actually isn't an equivalent refactoring.
The generic dm-device resolution procedure was modified to not resolve
the topmost dm-device in the path. So that any calles who don't expect
it, should complete the resolutioin process by themselves. In case of
chreipl_helper such completion was missed. chreipl(8) utility doesn't
expect dm-devices at the output of chreipl_helper.device-mapper
Example:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 20G 0 disk
|-sda1 8:1 0 20G 0 part
`-mpathb 253:0 0 20G 0 mpath
`-mpathb1 253:2 0 20G 0 part /
sdb 8:16 0 20G 0 disk
|-sdb1 8:17 0 20G 0 part
`-mpathb 253:0 0 20G 0 mpath
`-mpathb1 253:2 0 20G 0 part /
Expected result:
8:16
Actual result:
253:0
As a result, the chreipl(8) "node" option stopped working.
The fixup adds the completion.
