Subject: [PATCH 26/28] tests: Add udevadm settle to wait_for_ loop (#1260664)
|
|
|
003ee8 |
|
|
|
003ee8 |
Sometimes the device will vanish after the wait_for_dev_to_appear exits.
|
|
|
003ee8 |
Add udevadm settle in an attempt to make sure the udev system is done
|
|
|
003ee8 |
flapping around and the device will stay in place.
