    A common pattern with skb_put() is to just want to memcpy()
    some data into the new space, introduce skb_put_data() for
    this.

    of the places using it:

    "Here is the big staging and iio driver patchsets for 4.11-rc1.

    We almost broke even this time around, with only a few thousand lines
    added overall, as we removed the old and obsolete i4l code, but added
    some new drivers for the RPi platform, as well as adding some new IIO
    drivers.
