  • Commit outstanding metadata before returning the status for a dm thin
    pool so that the numbers reported are as up-to-date as possible.

    The commit is not performed if the device is suspended or if
    the DM_NOFLUSH_FLAG is supplied by userspace and passed to the target
    through a new 'status_flags' parameter in the target's dm_status_fn.

    The userspace dmsetup tool will support the --noflush flag with the
    'dmsetup status' and 'dmsetup wait' commands from version 1.02.76
    onwards.

  • This device-mapper target creates a read-only device that transparently
    validates the data on one underlying device against a pre-generated tree
    of cryptographic checksums stored on a second device.

    Two checksum device formats are supported: version 0 which is already
    shipping in Chromium OS and version 1 which incorporates some
    improvements.
