  * Try to remove an fscrypt master encryption key.
  *
  * FS_IOC_REMOVE_ENCRYPTION_KEY (all_users=false) removes the current user's
  * claim to the key, then removes the key itself if no other users have claims.
  * FS_IOC_REMOVE_ENCRYPTION_KEY_ALL_USERS (all_users=true) always removes the
  * key itself.
  *
- * To "remove the key itself", first we wipe the actual master key secret, so
- * that no more inodes can be unlocked with it.  Then we try to evict all cached
- * inodes that had been unlocked with the key.
+ * To "remove the key itself", first we transition the key to the "incompletely
+ * removed" state, so that no more inodes can be unlocked with it.  Then we try
+ * to evict all cached inodes that had been unlocked with the key.
  *
  * If all inodes were evicted, then we unlink the fscrypt_master_key from the
  * keyring.  Otherwise it remains in the keyring in the "incompletely removed"
  * state where it tracks the list of remaining inodes.  Userspace can execute
  * the ioctl again later to retry eviction, or alternatively can re-add the key.
  *
  * For more details, see the "Removing keys" section of
  * Documentation/filesystems/fscrypt.rst.
