nfs: count DIO good bytes correctly with mirroring When resending to MDS, we might resend multiple mirroring requests to MDS. As a result, nfs_direct_good_bytes() ends up counting bytes multiple times, causing application to get wrong return results in read/write syscalls. Fix it by tracking start of a dreq and checking the range of pgio header. Cc: Weston Andros Adamson <dros@primarydata.com> Signed-off-by: Peng Tao <tao.peng@primarydata.com>
