Btw, it might be a good idea to move to 4k sector size as the default, on pretty much any modern hardware sector sizes are 4k or larger internally, and 512 byte writes will always involve read-modify-write cycles. And unlike SATA or SCSI disks NVMe doesn't have a physical block size attribute, so we can't even look at that. -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
