    Subject[PATCH 5.10 044/152] dm integrity: fix the maximum number of arguments
    Date
    From: Mikulas Patocka <mpatocka@redhat.com>

    commit 17ffc193cdc6dc7a613d00d8ad47fc1f801b9bf0 upstream.

    all potential feature flags that may be supplied.

    (356d9d52e1221ba0c9f10b8b38652f78a5298329) and "recalculate"
    (a3fcf7253139609bf9ff901fbf955fba047e75dd) flags.

    Commit 468dfca38b1a6fbdccd195d875599cb7c8875cd9 added
    "sectors_per_bit" and "bitmap_flush_interval".

    Commit 84597a44a9d86ac949900441cea7da0af0f2f473 added
    "allow_discards".

    And the commit d537858ac8aaf4311b51240893add2fc62003b97 added
    "fix_padding".
