Why not all of them?
I initially only refactored nfs_errorf because it doesn't return a value.
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).
