For nfs_invalf, it will always return -EINVAL. Would you prefer me to refactor it using the ({ ... }) statement expression pattern to keep the return value, or is it better to leave it as is ?
I don't think in this case it improves the situation. Yeah, it's unfortunate.
#define nfs_invalf(fc, fmt, ...) ({ \
if ((fc)->log.log) \
invalf(fc, fmt, ## __VA_ARGS__); \I believe this already has an error code inside, that's why it's only added to the 'else' branch.
else \
dfprintk(fac, fmt "\n", ## __VA_ARGS__);\
-EINVAL; \
})Okay, let's go with your original approach (ideally these all probably should be replaced by static inline:s).
