Hi Christoph,

We did not modify 'device_is_integrity_capable' attribute.

Hi Everyone,

  * We have observed change in the values of some of the block integrity
    sysfs attributes for the block devices on the master branch. The
    sysfs attributes related to block device integrity , write_generate
    and read_verify are  enabled for the block device when the parameter
    device_is_integrity_capable is disabled. This behaviour is seen on
    the scsi disks irrespective of DIF protection enabled or disabled on
    the disks.

As in after a "echo 1 > /sys/.../device_is_integrity_capable" ?

I'll look into it.
