Hi all,

where does the kernel create the blktrace completion messages?

Is it done in the interrupt routine or in the block layer.

I just found:
register_trace_block_rq_complete(blk_add_trace_rq_complete, NULL);
and
register_trace_block_bio_complete(blk_add_trace_bio_complete, NULL);

But I don't find the corresponding functions.

Thanks,
Matthias

the mesage is created in block/blk-core.c:blk_update_request which calls 
trace_block_rq_complete
