Hi! I am trying to add fs-verity support for virtiofs. The main complication is that fs-verity ioctls do not have constant iovec lengths, so simply using _IOC_SIZE like with other ioctls does not work. Note this doesn't include support for FS_IOC_READ_VERITY_METADATA. I don't know of an existing use of it and I figured it would be better not to include code that wouldn't be used and tested. However if you feel like it should be added let me know. (Also, apologies for any mistakes as this is my first Linux patch!)
