Those improvement suggestions include: - Prefixing hashes for the DM tables being measured in ima log with the hash algorithm. - Adding version information for DM related events being measured in the ima log. - Prefixing DM related event names with "dm_". - Including the verity target attribute - "root_hash_sig_key_desc" in the ima measurement log. This series incorporates the above suggestions. This series also has the following fixes: - Adding a one-time warning to dmesg during dm_init if CONFIG_IMA_DISABLE_HTABLE is set to 'n'. - Updating 'integrity' target to remove the duplicate measurement of the attribute "mode=%c". - Indexing various attributes in 'multipath' target, and adding "nr_priority_groups=%u" attribute to the measurements. - Fixing 'make htmldocs' warnings in dm-ima.rst. - Adding missing documentation for the targets - 'cache', 'integrity', 'multipath', and 'snapshot' in dm-ima.rst. - Updating dm-ima.rst documentation with the grammar for various DM events and targets in Backus Naur form. - Updating dm-ima.rst documentation to be consistent with the code changes described above.
