Make a copy of both an &sk_buff and its data. This is used when the
caller wishes to modify the data and needs a private copy of the
data to alter. Returns NULL
on failure or the pointer to the buffer
on success. The returned buffer has a reference count of 1.
As by-product this function converts non-linear &sk_buff to linear one, so that &sk_buff becomes completely private and caller is allowed to modify all the data of returned buffer. This means that this function is not recommended for use in circumstances when only header is going to be modified. Use pskb_copy instead.
