Is there any feedback from block or LSM folk on the addition of a security blob for block_device here?
IPE uses this is to track the status of integrity verification of e.g. DM-Verity devices, per this code from a subsequent patch:
+ ret = security_bdev_setsecurity(dm_table_get_md(v->ti->table)->bdev, + DM_VERITY_SIGNATURE_SEC_NAME, + v->sig->sig, v->sig->sig_size);
