Bio error reporting has been a mess for a while, and the increasing use of chained bios makes it worse. Add a bi_error field to struct bio to fix this. Note that the rebase to 4.2-rc means a lot of context changes, so I've dropped the Reviewed-by tags from V2 as it will need a re-review. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
