I could just have this pattern:
Hi Kuai,
bio->bi_status = errno_to_blk_status(err);
set_bit(R1BIO_Uptodate, &r1_bio->state);
raid_end_bio_io(r1_bio);
I can live with this. 🙂
Is there a neater way to do this?
Perhaps add a new filed 'status' in r1bio? And initialize it to
BLK_STS_IOERR;
Then replace:
set_bit(R1BIO_Uptodate, &r1_bio->state);
to:
r1_bio->status = BLK_STS_OK;
So are you saying that R1BIO_Uptodate could be dropped then?
and change call_bio_endio:
bio->bi_status = r1_bio->status;
finially here:
r1_bio->status = errno_to_blk_status(err);
raid_end_bio_io(r1_bio);
Why not just set bio->bi_status directly?
Cheers,
John
