trace_block_split - split a single bio struct into two bio structs
void trace_block_split(struct request_queue * q, struct bio * bio, unsigned int new_sector);
The bio request bio in request queue q needs to be split into two bio requests. The newly created bio request starts at new_sector. This split may be required due to hardware limitation such as operation crossing device boundaries in a RAID system.
