Subject: [PATCH] udev: restore udevadm settle timeout
|
|
|
|
Commit 9ea28c55a2 (udev: remove seqnum API and all assumptions about
|
|
seqnums) introduced a regresion, ignoring the timeout option when
|
|
waiting until the event queue is empty.
|
|
|
|
Previously, if the udev event queue was not empty when the timeout was
|
|
expired, udevadm settle was returning with exit code 1. To check if the
|
|
queue is empty, you could invoke udevadm settle with timeout=0. This
|
|
patch restores the previous behavior.
|
|
|
|
(David: fixed timeout==0 handling and dropped redundant assignment)
|
|
|
|
(cherry picked from commit 0736455b1186c9515e0f093e1e686e684d225787)
