Have you got any more influence on the selection?

I assume that further software evolution will matter. Does an article like “The ORCs are coming” (by Jonathan Corbet from 2017-07-20) point information out which is also useful for this issue here? https://lwn.net/Articles/728339/ > Anyway, if we agree to change the way we allocate driver data here, > the issue this debate is about will no longer exist. Does your update suggestion contain still any additional error messages for memory allocation failures? Regards, Markus
