TRACE_BLOCK_BIO_BOUN(9)		   Block IO	       TRACE_BLOCK_BIO_BOUN(9)

NAME
       trace_block_bio_bounce - used bounce buffer when processing block
       operation

SYNOPSIS
       void trace_block_bio_bounce(struct request_queue * q,
				   struct bio * bio);

ARGUMENTS
       q
	   queue holding the block operation

       bio
	   block operation

DESCRIPTION
       A bounce buffer was used to handle the block operation bio in q. This
       occurs when hardware limitations prevent a direct transfer of data
       between the bio data memory area and the IO device. Use of a bounce
       buffer requires extra copying of data and decreases performance.
