etc ``const void *value`` the integrity value ``size_t size`` size of the integrity value **Description** Register a verified integrity measurement of a bdev with LSMs. LSMs should free the previously saved data if **value** is NULL. Please note that the new hook should be invoked every time the security information is updated to keep these data current. For example, in dm-verity, if the mapping table is reloaded and configured to use a different dm-verity target with a new roothash and signing information, the previously stored data in the LSM blob will become obsolete. It is crucial to re-invoke the hook to refresh these data and ensure they are up to date. This necessity arises from the design of device-mapper, where a device-mapper device is first created, and then targets are subsequently loaded into it. These targets can be modified multiple times during the device's lifetime. Therefore, while the LSM blob is allocated during the creation of the block device, its actual contents are not initialized at this stage and can change substantially over time. This includes alterations from data that the LSMs 'trusts' to those they do not, making it essential to handle these changes correctly.
