So... here, I think the problem with Manuel's 2002 patch (which has
been committed at some point) is that it wasn't meant to deal with an
error condition. But I note that st.c now has this in stdone:
bp->b_error = error;
bp->b_resid = xs->resid;
* buggy device ? A SDLT320 can report an info
* field of 0x3de8000 on a Media Error/Write Error
* for this CBD: 0x0a 00 00 80 00 00
if (bp->b_resid > bp->b_bcount || bp->b_resid < 0)
bp->b_resid = bp->b_bcount;
which will both avoid a panic and also prevent upper-layer code from
thinking the write went through.
So I think this PR can be closed. Manuel? Anyone else? Is the
submitter still around?
