Subject: [PATCH] udev: warn when name_to_handle_at is not implemented
|
||
|
|
|
||
|
|
We have a bunch of reports from people who have a custom kernel and
|
||
|
|
are confused why udev is not running. Issue a warning on
|
||
|
|
error. Barring an error in the code, the only error that is possible
|
||
|
|
is ENOSYS.
