dm-integrity: introduce the Inline mode

Browse Source

This commit introduces a new 'I' mode for dm-integrity.

The 'I' mode may be selected if the underlying device has non-power-of-2
sector size. In this mode, dm-integrity will store integrity data
directly in device's sectors and it will not use journal.

This mode improves performance and reduces flash wear because there would
be no journal writes.
