confirmed.

commit 1883088ed4a0d5cc9cea500ca4e89a354ab32c11

    md: bcache: check the return value of kzalloc() in detached_dev_do_requ=
est()

    commit 40f567bbb3b0639d2ec7d1c6ad4b1b018f80cf19 upstream.

    The function kzalloc() in detached_dev_do_request() can fail, so its
    return value should be checked.

    Fixes: bc082a55d25c ("bcache: fix inaccurate io state for detached
bcache devices")
