Detailed Description

Structure used as parameter for dm-integrity device type.

See also: crypt_format, crypt_load

Note: In bitmap tracking mode, the journal is implicitly disabled. As an ugly workaround for compatibility, journal_watermark is overloaded to mean 512-bytes sectors-per-bit and journal_commit_time means bitmap flush time. All other journal parameters are not applied in the bitmap mode.
