5e5d48348b man lvmcache: updates for mode and policy
Correct some things, e.g. set mode and policy on
the cache lv, not the pool, lvm.conf field for
mode changed.

Add smq which was missing.

Make the sections on cache mode and cache policy
consistent in structure and style.

cb82919b0d systemd: use {local,remote}-fs-pre.target instead of {local,remote}-fs.target
We want most of our units to be started before any local/remote mount
points are mounted - we used {local,remote}-fs.target for this purpose
before, but it was not 100% correct as there's even {local,remote}-fs-pre.target
special systemd unit reserved for this exact purpose.

See also man 7 systemd.special and "local-fs-pre.target"/"remote-fs-pre.target"
description.

Start to use 'italic' when the argument is not a fixed string.

cebbb0feaf dmstats: replace histogram command with switch
Replace the histogram stats subcommand with a --histogram switch
to enable histogram related fields for both list and report output.

To avoid overloading the existing --histogram rename it to --bounds:
this is also a better description of the option.

3c0fc6f0da dmstats: add histogram support
Add support to dmstats to create and report histograms.

Add a --histogram switch to 'create' that accepts a string
description of bin boundaries and DR_STATS and DR_STATS_META fields
to report bin configuration and absolute and relative histogram
values:

  hist_bins
  hist_bounds
  hist_ranges
  hist_count
  hist_count_bounds
  hist_count_ranges
  hist_percent
  hist_percent_bounds
  hist_percent_ranges

A new 'histogram' subcommand displays a report that emphasizes
histogram data as either counters or percentage values.

f3891e90e3 dmstats: make -v enable per area reports for 'stats list'
When dmstats is run with -v or higher enable a per-area reporting
mode for statistics regions. This will output one row per area
(rather than one row per region) and adds additional fields of use
when viewing areas:

 area_id    - index within the region assigned by libdm-stats
 area_start - the start location of the area in the containing
              device.

9b3dc72506 dmstats: add 'interval' and 'interval_ns' report fields
Add a pair of fields to expose the current per-interval duation
estimate. The 'interval' field provides a real value in units of
seconds and the 'interval_ns' field provides the same quantity
expressed as a whole number of nanoseconds.

6b81ac5807 dmstats: replace --force with new stats-specific --alldevices
The '--force' switch is only used by dmstats to allow either
creation or deletion of one or more regions on all devices.

These operations do not carry any risk: just a possible mess of
region IDs to be cleaned up.

Remove the use of '--force' for stats commands and change current
uses to a new '--alldevices' switch.

d62a8d2f15 dmstats: add libdm-stats library and 'dmsetup stats' command
Add the libdm-stats module to libdm: this implements a simple interface
for creating, managing and interrogating I/O statistics regions and
areas on device-mapper devices.

The library interface is documented in libdevmapper.h and provides a
'dm_stats' handle that is used to perform statistics operations and
obtain data.

Public methods are provided to create and destroy handles and to list,
create, and destroy statistics regions as well as to obtain and parse
counter data and calculate rate-based metrics.

This commit also adds a 'dmsetup stats' (aka 'dmstats') command with
'clear', 'create', 'delete', 'list', 'print', and 'report' sub-commands.

See the library documentation and the dmstats.8 manual page for detailed
API and command descriptions.
