btrfs_end_bio() is using btrfs_dev_stat_inc() and then btrfs_dev_stat_print_on_error() separately instead use btrfs_dev_stat_inc_and_print() directly.
No need to worry about print lines one for read/write and another if the source of IO request is flush, since as mentioned in this patch [patch] btrfs: REQ_PREFLUSH does not use btrfs_end_bio() completion callback there isn't any IO which is doing that. This consolidation is a preparatory patch to add device critical error handling in btrfs_dev_stat_inc_and_print() and can be renamed as needed.
