From: Andi Kleen <redacted> Only a single b_private field in the map_bh buffer head is needed after the submission path. Move map_bh separately to avoid storing this information in the long term slab. This avoids the weird 104 byte hole in struct dio_submit which also needed to be memseted early. v2: b_private->private (hch) Signed-off-by: Andi Kleen <redacted>

So long as that zeroes the entire struct (seems to), I'm okay with this patch. Cheers, Jeff
