    ext4: remove unnecessary bio get/put · 32157de2
    Jens Axboe authored
    ext4_io_submit() used to check for EOPNOTSUPP after bio submission,
    which is why it had to get an extra reference to the bio before
    submitting it. But since we no longer touch the bio after submission,
    get rid of the redundant get/put of the bio. If we do get the extra
    reference, we enter the slower path of having to flag this bio as now
    having external references.
