Change ENOTSUPP to EOPNOTSUPP Because that is what you get if a BIO_RW_BARRIER isn't supported !
Dumb question, hope someone can answer it :). Does this mean that any version of MD up till now won't know that SATA disks does not support barriers, and therefore won't flush SATA disks and therefore I need to disable the disks's write cache if I want to be 100% sure that raid arrays are not corrupted? Or am I way off :-). - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
