I was assuming that we would reset one zone at a time, which I think is the main way this would be used. Thinking about this some more, one other way we could do is to reuse BLKDISCARD, with the restriction that the starting LBA (offset) must be the first LBA for a zone, and offset + length - 1 must be last LBA for a zone. If either of these restrictions are violated, then BLKDISCARD would return EINVAL --- or maybe some other error code, since EINVAL can also mean an invalid ioctl code. Hmm... ERANGE would be good, but the strerror(ERANGE) returns "Math result not representable", which would be highly confusing, although it falls within the grand tradition of confusing Unix error messages, such as "not a typewriter". :-) Any other suggestions? - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
