Subject: [PATCH] udevadm-trigger: also check with the original syspath if
|
||
|
|
device is renamed
|
||
|
|
|
||
|
|
For older kernels that synthetic UUID is not supported, we need to also
|
||
|
|
check the original device name, as udevd broadcasts uevent with new
|
||
|
|
sysname.
|
||
|
|
|
||
|
|
Fixes #25115.
|
||
|
|
|
||
|
