[openib-general] SDP_IOCB_SIZE_MAX

[Michael S. Tsirkin]

Libor, in sdp_iocb.h we have:

sdp_iocb.h:#define SDP_IOCB_SIZE_MAX (128*1024) /* matches AIO max kvec size. */

What does the comment mean?

I seem to have no trouble passing requests bigger than 128K to SDP:

./ttcp.aio.x -r -l 1000000 -a 20
./ttcp.aio.x -t -l 1000000 -n 1000000 -a 20 11.4.8.155

gets:

# dmesg
ib_sdp  ERR: IOCB <0> cancel <0> flag <0140> size <1000000:0:1000000>
ib_sdp  ERR: IOCB <0> cancel <0> flag <0140> size <1000000:0:1000000>
