Subject: [PATCH 8/54] sysoff: Change log level of ioctl error messages.
|
|
|
|
Change the log level of ioctl error messages to the error level to make
|
|
them visible in default configuration, with the exception of EOPNOTSUPP
|
|
which is expected in probing and should stay at the debug level to avoid
|
|
confusing users.
