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 ?
#define nfs_invalf(fc, fmt, ...) ({ \
if ((fc)->log.log) \
invalf(fc, fmt, ## __VA_ARGS__); \
else \
dfprintk(fac, fmt "\n", ## __VA_ARGS__);\
-EINVAL; \
})
