be3f666ef3 lv_manip: improve should_wipe reporting
We want to print smarter warning message only when
the zeroing was not provided on the first zeroable segment
of newly created LV.

Put warning within _should_wipe_lv function to avoid reevaluation
of same conditions twice.

Ask for lock the proper LV.
Use the top-most LV to query for locally exclusive lock.

TODO:
  Check all devices are reloaded from proper level.
  In general any query on lv_is_active is supposed to be running

9351dca863 report: fix selection on {vg,lv}_permissions fields to properly match selection criteria
There was a bug in value and their synonym definition for these two fields
causing selections on these fields to not work correctly - nothing matched
against vg/lv_permissions fields even if selection criteria should have
matched.

Scenario:
$ lvs -o name,lv_permissions vg
  LV    LPerms
  lvol0 read-only
  lvol1 writeable

Before this patch:

$ lvs -o name,lv_permissions vg -S 'permissions=read-only'
(blank)
$ lvs -o name,lv_permissions vg -S 'permissions=writeable
(blank)

With this patch applied:

$ lvs -o name,lv_permissions vg -S 'permissions=read-only'
  LV    LPerms
  lvol0 read-only
$ lvs -o name,lv_permissions vg -S 'permissions=writeable'
  LV    LPerms
  lvol1 writeable

Also synonyms match correctly now:
$ lvs -o name,lv_permissions vg -S 'permissions=rw'
  LV    LPerms
  lvol1 writeable

4b611bb816 report: lv_permissions: display read-only/read-only-override instead of blank when LV is not writeable
Before this patch:
$ lvs -o name,lv_attr,lv_permissions
  LV    Attr       LPerms
  root  -wi-ao---- writeable
  swap  -wi-ao---- writeable
  lvol0 -Ri-a-----
  lvol1 -ri-a-----
  lvol2 -wi-a----- writeable
  lvol3 -ri-------

With this patch applied:
$ lvs -o name,lv_attr,lv_permissions
  LV    Attr       LPerms
  root  -wi-ao---- writeable
  swap  -wi-ao---- writeable
  lvol0 -Ri-a----- read-only-override
  lvol1 -ri-a----- read-only
  lvol2 -wi-a----- writeable
  lvol3 -ri------- read-only

("read-only-override" is displayed if the "writeable" permission
is overriden based on "activation/read_only_volume_list" lvm.conf
setting)

c87e5a308a filter-usable: filter out blocked and suspended devices firmly when scanning for lvmetad
We can't hang on blocked or suspended devices when the scan is done
for lvmetad update - when the device gets unblocked or resumed, there's
always CHANGE event generated which will fire the udev rule to run
extra pvscan --cache for that device which makes sure that lvmetad
is up-to-date.

0cbb381e15 lvcreate: regression fix on lv name limits
When we are given an existing LV name - it needs to be allowed
to pass in even restricted name as the LV could have existed
long before we introduced some new restriction on prefix/suffix.i

Fix the regression on name limits and drop restriction to be applied
on any existing LVs - only the new created LV names have to be
complient with current name restrictions.

FIXME: we are currently using restricted names incorrectly in few
other places - device_is_usable() skips restricted names,
and udev flags are also incorrectly set for restricted names
so these LVs are not getting links properly.

888da17495 metadata: add internal error if PV has no existing device attached during find_pv_in_vg
find_pv_in_vg fn iterates over the list of PVs covered by the VG and
each PV's pvl->pv->dev is compared with device acquired from device
cache. However, in case pvl->pv->dev is NULL as well as device cache
returns NULL (e.g. when device is filtered), we'll get incorrect match
and the code calling find_pv_in_vg uses incorrect PV (as it thinks
it's the exact PV with the pv_name). The INTERNAL_ERROR covers this
situation and errors out immediately.

8dc5f42254 metadata: Use flags to control warnings.
The warnings arg was used to enable logging of warnings
when reading a PV.  This arg is turned into a set of flags
with the WARN_PV_READ flag matching the existing behavior.

A new flag WARN_INCONSISTENT is added that will cause
vg_read_internal() to log the "VG is not consistent"
warning so the various callers do not need to log
this warning themselves.

A new vg_read flag READ_WARN_INCONSISTENT is used from
reporting to enable the WARN_INCONSISTENT flag in
vg_read_internal.

f1a000a477 toollib: Rewrite process_each_pv.

devices if the command needs to process non-PV devices.
The process_single function can always use the VG and PV args.

d46c2f1c94 cache: improve creation code
Move code to better locations.
Improve test and remove invalid ones
(i.e. no reason to require cache size to be >= then origin).

Correctly comment where the code is doing actual conversion
of other existing volume - we do already a similar thing with
external origins.

Lots of new command line options and combinations is now supported.
Hopefully older syntax still works as well.

lvcreate --cache --cachepool vg/pool  -l1
lvcreate --type cache --cachepool vg/pool  -l1
lvcreate --type cache-pool vg/pool  -l1
lvcreate --type cache-pool --name pool vg  -l1
... and many many more ...

17ab39f743 cache: include cache mode in vg metadata and display
The cache mode of a new cache pool is always explicitly
included in the vg metadata.  If a cache mode is not
specified on the command line, the cache mode is taken
from lvm.conf allocation/cache_pool_cachemode, which
defaults to "writethrough".

The cache mode can be displayed with lvs -o+cachemode.
