| Subject: [PATCH 46/83] tests/00readonly: Run udevadm settle before setting ro
 | |
| 
 | |
| In some recent kernel versions, 00readonly fails with:
 | |
| 
 | |
|   mdadm: failed to set readonly for /dev/md0: Device or resource busy
 | |
|   ERROR: array is not read-only!
 | |
| 
 | |
| This was traced down to a race condition with udev holding a reference
 | |
| to the block device at the same time as trying to set it read only.
 | |
| 
 | |
| To fix this, call udevadm settle before setting the array read only.
