No, do not create new types of error or return codes. Use the standard
-EFOO values. You can document what they should each return, and mean,
but do not create new codes.
Also, you create an enum, but yet do not use it in your function
callback definition, which means you really didn't want to create it in
the first place...
I'll add 15 and 16 to my tree for now, so they will show up in -mm, but
I want to see updated versions before sending them off to Linus.
thanks,
