Hi,
Some more comments from reviewing patch 4 in this set.

Rather than scanning /dev/disk/by-path directly, check the udev database
for the PATH_ID or ID_PATH or whatever it's called that gives us the
devlink name that would appear in /dev/disk/by-path. Sometimes the
links in /dev/disk/by-path do not appear because you have them already
in /dev/disk/by-id (or not, who knows?). At any rate, stop checking the
/dev/disk/by-path directory manually and just ask udev.

You cannot simply convert a path to a name this way, instead
you should use devicePathToName, or better fix all callers
of deviceNameToDiskByPath to pass in a name as the function
name suggests. You're already doing this for the
usage in dasd.py, this only leaves one usage in
devices.py PartitionDevice.fstabSpec() and one usage
in devicetree.py to fixup.
Regards,
Hans
