The change is incomplete, if you want to replace 0 by BLK_STS_OK, you should check all locations where s->iop.status is checked and replace with BLK_STS_OK when necessary. One but not the only one example is, 871 if (s->iop.status) 872 continue_at_nobarrier(cl, cached_dev_read_error, bcache_wq); Maybe you should change to if (s->iop.status != BLK_STS_OK) continue_at_nobarrier(cl, cached_dev_read_error, bcache_wq); Just FYI.
