Hi Jens,
Can we perhaps backport this to stable kernels as well? In particular, to
long-term kernel 4.14.
Thanks,
Alex.

"bio: skip atomic inc/dec of ->bi_cnt for most use cases"
made __bi_cnt dependent on the new BIO_REFFED flag.
bio_reset() does not reset __bi_cnt, but it does reset the BIO_REFFED
flag.
But __bi_cnt depends now on the BIO_REFFED flag, so bio_reset()
needs to preserve this flag.
Looks good to me, applied, thanks.
