Description

We often face the very weird message "is it ok to have flags 0x... and 0x... in the same brw?".
It seems this message is not a real issue, the system seems stable. So, this is not a CERROR().

This message has no meaning for any Lustre administrators, only for Lustre developpers.
As Lustre has a long history of having un-understandable error messages, it could be nice to do something better here.
