It performs no\nvalidation on the result, while the constructor validates the superblock\nit reads and sizes all the in-memory structures according to it. The user\nmay modify the superblock on the underlying device while the dm-integrity\ndevice is suspended, so that the two no longer agree.\n\nIn particular, access_journal_data() shifts the journal entry index by\nic->sb->log2_sectors_per_block, while ic->journal_section_sectors and the\njournal page list were computed with the value that was present at\nconstructor time. Increasing log2_sectors_per_block makes the index run\npast the end of the journal, and dm-integrity then writes 512 bytes\nthrough lowmem_page_address(NULL).\n\nSnapshot the validated superblock in the constructor and refuse to resume\nif any of the fields that describe the on-disk geometry changed."
