8   Set up a bio_set to be used with <em class="parameter"><code>bio_alloc_bioset</code></em>. Allows the caller
9   to ask for a number of bytes to be allocated in front of the bio.
10   Front pad allocation is useful for embedding the bio inside
11   another structure, to avoid allocating extra data to go with the bio.
12   Note that the bio must be embedded at the END of that structure always,
13   or things will break badly.
