Hi all, Just a gentle ping to see if there’s any feedback on this patch. I'm happy to address any comments.Thanks for your time! On 2024/12/19 23:07, Guoyi Tu wrote:

this commit addresses the same issue that as commit 1af45804 does.

the following message is copying from that commit:   If we find ourselves in the situation that the 'add' uevent has been   fired earlier than the sysfs tree for a device was created, we should   use the best-effort approach and give kernel some predetermined amount   of time, thus waiting for the attributes to be ready rather than   discarding the device from our device list forever. If those don't appear   in the given time frame, we need to move on, since libvirt can't wait   indefinitely.
