| Subject: [PATCH 3/3] BmapCopy.py: tweak suggested udev rule |
| |
| Both bdi/max_ratio and queue/scheduler are only valid for whole block devices, |
| not individual partitions. Therefore, add a |
| |
| ENV{DEVTYPE}!="partition", |
| |
| to the suggested udev rule so that bmaptool doesn't try to check every |
| partition of the block device, just the whole device. |
| |
| Otherwise the following will appear in the logs: |
