For direct read that has IO size larger than rsize, we'll split it into several READ requests and nfs_direct_good_bytes() would count completed bytes incorrectly by eating last zero count reply. Fix it by handling mirror and non-mirror cases differently such that we only count mirrored writes differently. This fixes 5fadeb47("nfs: count DIO good bytes correctly with mirroring"). Reported-by:
