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.
