NAME
       blk_integrity_compare - Compare integrity profile of two disks

SYNOPSIS
       int blk_integrity_compare(struct gendisk * gd1, struct gendisk * gd2);

ARGUMENTS
       gd1
           Disk to compare

       gd2
           Disk to compare

DESCRIPTION
       Meta-devices like DM and MD need to verify that all sub-devices use the same integrity
       format before advertising to upper layers that they can send/receive integrity metadata.
       This function can be used to check whether two gendisk devices have compatible integrity
       formats.
