    dm thin: commit before gathering status · 1f4e0ff0
    Alasdair G Kergon authored
    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
