This lacks a trace...

...that was present here. And you didn't do straight code motion, but
modified things on the way (hence why checkpatch complained that your
more concise version is suspicious with regards to returning positive
errno). Does the function still need to be static inline, or should we
just declare a prototype in the header and put the function itself in
nbd/common.c?
