      .The VDO `sysfs` parameters have been deprecated

      The Virtual Data Optimizer (VDO) `sysfs` parameters have been deprecated and will be removed in a future major RHEL release. Except for `log_level`, all module-level `sysfs` parameters for the `kvdo` module will be removed.
      For individual `dm-vdo` targets, all `sysfs` parameters specific to VDO will also be removed. There is no change for the parameters that are common to all DM targets. Configuration values for `dm-vdo` targets, which are currently set by updating the removed module-level parameters, can no longer be changed.

      Statistics and configuration values for `dm-vdo` targets will no longer be accessible through `sysfs`. But these values are still accessible by using `dmsetup message stats`, `dmsetup status`, and `dmsetup table` dmsetup commands

      All sysfs fields in kvdo need to be deprecated in the RHEL 9 because we intend to remove them in the future.

      The information available through the sysfs fields is still available through other channels, such as 'dmsetup message stats'.
