Subject: [PATCH] udev: Fix ping timeout when settle timeout is 0
|
|
|
|
|
|
|
|
|
|
When running udevadm settle --timeout=0, the ping always times out, and
|
|
|
|
|
udevadm will return 0 without checking the queue state.
|
|
|
|
|
|
|
|
|
|
(David: Use a reasonable timeout to still get the barrier provided by
|
|
|
|
|
ctrl-ping)
|
|
|
|
|
|
|
|
|
