Hi Neil, Looking through the code in mdadm, I noticed a number of cases calling ioctl(RAID_VERSION). At first I had it confused with metadata version, but it looks like RAID_VERSION will always return 90000 if it's a valid raid device. In the cases we want to confirm the fd is a valid raid array, ioctl(GET_ARRAY_INFO) should do, or sysfs_read(GET_VERSION). Am I missing something obvious here, or do you see any reason for leaving this around?
