Regarding the name, same name for ioctl and command is a good idea, for
potential future verity extensions we could add more and having plain
'VERITY' would not be ideal. The other ioctl is 'measure', so I thought
of something like consistency check during the stream, "verify this
file before continuing".
The command names are either imperative or descriptive, so alternative
name could be VERITY_RECORD or VERITY_DESC that matches the data stored,
the BTRFS_VERITY_DESC_ITEM_KEY .
