-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I captured a trace with blktrace -d /dev/sde -d /dev/sdf -o - > trace, then parsed it with blkparse -i - < trace, and I have noticed that the events are out of order. They appear to come in batches from one cpu, then the other, and when transitioning from one batch to the other, the timestamps roll backwards. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBCgAGBQJUo1a3AAoJENRVrw2cjl5RPEYH/1q7V0fKvMXRtGWtaHrxkefp Wzjyh8MekQL2gRROq0Fa7pjwUtGAsfuFW9K8RmFtJaNBemM+zWRXkF7vX6CPjVG+ IqO65M628b12A/GLmwPkK1vZ4qM/x2SE9h+JpUH068QUKQw+EyEVEIxrflC6al+S LBY/mST0HOFog3dYOK7Bx6rKbRfyNOiw729xltq8Vpwn5HVHl3R3ZzvFir1ZV1VX 2foZquHEfFJsb9hHE4QZylBCqLE6txFnAW6PitqNtJyy8ow82Q+gyw2xSeTvxGJH 4KDWVbsTLYRihIf1dg+Uk7gEfIejO21H8Cb/O33RD7iHQO+uyuaE1UP9TNgyS6w= =hj/D -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-btrace" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
