  • How was this pull request tested?
    RHEL 7, 8 and 9 systems were recovered and checked via xfs_db that features_ro_copmat and
    features_incompat are left the same as on the original systems. Additionally, checked via xfs_info that new features keep original enablement status.

  • Description of the changes in this pull request:
    Recognize the following XFS features from the xfs_info output: rmapbt, reflink, bigtime, inobtcount, nrext64 and sparse, and preserve their original enablement status. In newer version of mkfs.xfs, these options are enabled by default, which is not the desired behaviour if they were intentionally disabled.

@rear/contributors
could you please have a look here
(as time permits).

I am not an experienced XFS user
so I cannot properly review it.
