a3a5f58c21 reporting: Add devtypes command.
Add internal devtypes reporting command to display built-in recognised
block device types.  (The output does not include any additional
types added by a configuration file.)

  Device Types Fields
  -------------------
    devtype_all            - All fields in this section.
    devtype_name           - Name of Device Type exactly as it appears in /proc/devices.
    devtype_max_partitions - Maximum number of partitions. (How many device minor numbers get reserved for each device.)
    devtype_description    - Description of Device Type.

80bcdb93ff filters: check for mpath before opening devs
Split out the partitioned device filter that needs to open the device
and move the multipath filter in front of it.

When a device is multipathed, sending I/O to the underlying paths may
cause problems, the most obvious being I/O errors visible to lvm if a
path is down.

Revert the incorrect <backtrace> messages added when a device doesn't
pass a filter.

Log each filter initialisation to show sequence.

Avoid duplicate 'Using $device' debug messages.

9775a19af1 lib/properties: Common code for handling properties.
The common bits from lib/report/properties.[c|h] have
been moved to lib/properties/prop_common.[c|h] to allow
re-use of property handling functionality without
polluting the report handling functionality.

7c6526aae2 lvresize: separate validation from action
Start separating the validation from the action in the basic lvresize
code moved to the library.
Remove incorrect use of command line error codes from lvresize library
functions.  Move errors.h to tools directory to reinforce this,
exporting public versions of the error codes in lvm2cmd.h for dmeventd
plugins to use.

c6f48b7c1a refactor: make device type recognition code common for general use
Changes:

- move device type registration out of "type filter" (filter.c)
to a separate and new dev-type.[ch] for common use throughout the code

- the structure for keeping the major numbers detected for available
device types and available partitioning available is stored in
"dev_types" structure now

- move common partitioning detection code to dev-type.[ch] as well
together with other device-related functions bound to dev_types
(see dev-type.h for the interface)

The dev-type interface contains all common functions used to detect
subsystems/device types, signature/superblock recognition code,
type-specific device properties and other common device properties
(bound to dev_types), including partitioning support.

- add dev_types instance to cmd context as cmd->dev_types for common use

- use cmd->dev_types throughout as a central point for providing
information about device types

e947c362dd config: add config_settings.h
This file centrally defines all recognized LVM2 configuration
sections and settings. Each item here has its parent, set of
allowed types, default value, brief comment, version the setting
first appeared in and flags that further define the nature of
the configuration setting and its use.

07113beea3 Do not scan device if it is part of active multipath.
Add filter which tries to check if scanned device is part
of active multipath.

Firstly, only SCSI major number devices are handled in filter.

Then it checks if device has exactly one holder (in sysfs) and
if it is device-mapper device and DM-UUID is prefixed by "MPATH-".

If so, this device is filtered out.

The whole filter can be switched off by setting
mpath_component_detection in lvm.conf.

b171907fc5 Refactor metadata.[ch] into lv.[ch] for lv functions.
This patch is similar to the other patches for pv and vg
functionality, and separates lv functionality into separate
files, concentrating on reporting fields and simple functions.

f42b708eae Refactor metadata.[ch] into pv.[ch] for pv functions.
The metadata.[ch] files are very large.  This patch makes a first
attempt at separating out pv functions and data, particularly
related to the reporting fields calculations.

More code could be moved here but for now I'm stopping at reporting
functions 'get' / 'set' functions.

fc65b9038e Add properties.[ch] to lib/report, defined based on columns.h.
Extend the existing reporting infrastructure definitions and structures
to include a 'get' and 'set' function for each field.  We will provide
a 'get' and 'set' function for each of these fields, which will be utilized
by exported lvm2app functions.

Define a default _not_implemented 'get' and 'set' function that just sets
an errno and returns 0.  Future patches will actually implement the
specific 'get' and 'set' functions for each property.  For read-only
properties, only the 'get' function will be implemented.

Define vg_get_property() function to query a property.  We will call
this from a lvm2app function.

8f26e18c13 Cluster log daemon (clogd): use LVM bitops in place of ext2 bitops
Eliminate dependency on outside library, since the same functionality
exists in our tree.

[It is important that the bitops work in the same way, as the bitmaps
must remain backwards compatible.  I haven't tested every architecture,
but the x86* archs work.  My test involved using the old ext2fsprogs
bitops, memcpy'ing the bits over to the LVM bitset array and ensuring
that only the bits set via the old methods were set.]

0b502933c5 Introduce lvm2_install target.
Buildsystem support device-mapper only install,
but generic install tagret includes both dm+lvm2.

For distribution which uses separate install_device-mapper,
there is no way how to install lvm2 only
(so after installing lvm2 for packaging purposes
built system must remove installed device-mapper files).

Fix it by allowing lvm2_install target, similarily like
install_cluster for clvmd.

(install = install_device-mapper + install_lvm2)
