To interpret various DM target measurement data in IMA logs,
a separate documentation page is needed under
Documentation/admin-guide/device-mapper.
Add documentation to help system administrators and attestation
client/server component owners to interpret the measurement
data generated by various DM targets, on various device/table state
changes.

bio-based configurations that don't haave a SCSI device handler.
- Fix dm-btree removal to ensure non-root btree nodes have at least
(max_entries / 3) entries. This resolves userspace thin_check
utility's report of "too few entries in btree_node".
- Fix both the DM thin-provisioning and dm-clone targets to properly
flush the data device prior to metadata commit. This resolves the
potential for inconsistency across a power loss event when the data
device has a volatile writeback cache.
- Small documentation fixes to dm-clone and dm-integrity.

Pull device mapper fixes from Mike Snitzer:
- Fix DM multipath by restoring full path selector functionality for
bio-based configurations that don't haave a SCSI device handler.
- Fix dm-btree removal to ensure non-root btree nodes have at least
(max_entries / 3) entries. This resolves userspace thin_check
utility's report of "too few entries in btree_node".
- Fix both the DM thin-provisioning and dm-clone targets to properly
flush the data device prior to metadata commit. This resolves the
potential for inconsistency across a power loss event when the data
device has a volatile writeback cache.
- Small documentation fixes to dm-clone and dm-integrity.
* tag 'for-5.5/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
docs: dm-integrity: remove reference to ARC4
dm thin: Flush data device before committing metadata
dm thin metadata: Add support for a pre-commit callback
dm clone: Flush destination device before committing metadata
dm clone metadata: Use a two phase commit
dm clone metadata: Track exact changes per transaction
dm btree: increase rebalance threshold in __rebalance2()
dm: add dm-clone to the documentation index
dm mpath: remove harmful bio-based optimization
Convert the dm-dust documentation to ReST formatting, using literal
blocks for all of the shell command, shell output, and log output
examples.
Add dm-dust to index.rst.
Additionally, fix an annotation in the "querying for specific bad
blocks" section, on the "queryblock ... not found in badblocklist"
example, to properly state that the message appears when a given
block is not found.
