Subject: [PATCH] udev: settle should return immediately when timeout is 0
|
|
|
|
|
|
|
|
|
|
udevadm manual says:
|
|
|
|
|
|
|
|
|
|
A value of 0 will check if the queue is empty and always return
|
|
|
|
|
immediately.
|
|
|
|
|
|
|
|
|
|
However, currently we ignore the deadline if the value is 0, and wait
|
|
|
|
|
without any limit.
|
|
|
|
|
|
|
|
|
|
Zero timeout behaved according to the documentation until commit
|
|
|
|
|
ead7c62ab7 (udevadm: settle - kill alarm()). Looking at this patch, it
|
|
|
|
|
seems that the behavior change was unintended.
|
|
|
|
|
|
|
|
|
|
This patch restores the documented behavior.
