Jamie, please send a v6 of this patch alone[*], where you print the
return value as Dmitry suggested . You do print it in a similar
statement of the subsequent patch, so this makes even more sense.

FWIW I'd already take the patch as it is and consider it a readability
improvement, but I now realize that the suggestion of not calling
functions in conditions is not mentioned anywhere in
Documentation/CodingStyle, so maybe I would just be over-zealous.

Ciao,
   Antonio
