Hi,

I'm trying to re-use struct bio after completion, including the
allocated pages. Normally I re-initialize the fields bi_sector,
bi_size, bi_next, bi_flags, bi_comp_cpu and bi_bdev.
This works perfectly well, as long as no media errors are encountered.
After a media error, all subsequent reads with this bio fail. Are
there any more fields that need to get re-initialized? Or, better,
is there a function to reset the bio?

Thanks,
Arne
