2419345b9d pvremove: use consistent error message
When the device is not a PV print
  "No PV found on device ..."

4dc5d4ac7e label_read_pvid: separate error and no-pvid
error reading dev and no pvid on dev were both
returning 0.  make it easier for callers to
know which, if they care.

return 1 if the device could be read, regardless
of whether a pvid was found or not.
set has_pvid=1 if a pvid is found and 0 if no
pvid is found.

fcbed26393 Revert "cov: check label_read_pvid return value"
This reverts commit bf461b99c6.

label_read_pvid returns 0 for non-PVs and these callers want
to handle non-PVs.

64a8505b96 tests: use should for expected state
While we heavily try to spot arrays that are not yet in-sync,
some kernels tends to block our lvm2 command in kernel,
while we resume these smaller raid arrays even for 5 seconds.

But since the result is not really wrong - report these
check failures only as TEST WARNING.

579c941321 man: document fsadm -l option
Missed -l option in man page, although users should prefer
lvresize -r when the also want to do a volume management,
as there they can specify i.e. extents for allocation.
Also mention dm-crypt support in command description.

cfe26470e3 dev-cache: change message level to debug
This case happens when i.e. we convert LV to another type,
when we change existing LV into a different type - so change
to debug level and avoid confusing users with message about
Device path  not match.

We may eventually enhnace caching code to drop cached info
after taking lock and reading VG.

5e8307f4bf lvmcache: fix memory leak
With commit 0b18c25d93 there
was introduced  'zalloc()' for allocation of outdates pvs,
but no matching  'free()' is present.
Switch to use cmd mempool instead of adding free() code into
several places.

d651b340e6 commands: use AUTOTYPE in definitions
If a cmd def implies an LV type without --type
in the required options, then include the implied
type in the cmd def as AUTOTYPE: <type>
instead of including the redundant --type foo
in the OO list of options.

Including an implied --type in the OO list would
often cause multiple cmd defs to potentially be
identical when options were used, and a user
command could match more than one cmd def.

The AUTOTYPE values are listed in man page and
help output as
 [ --type foo (implied) ]

If a user command includes --type, it will usually
match a cmd def with --type in the required options.
But, if the user command matches a cmd def with
AUTOTYPE, then the specifed --type and AUTOTYPE must
match.

The man-generator program has a new --check
option that compares cmd defs to find any cmd defs
that are equivalent with the use of options,
and should have their options adjusted.

7b77226df2 man-generator: add option to check for repeated command definitions
Compares cmd defs based on two principles for avoiding repeated
commands (where a given command could match more than one cmd def):

. a cmd def should be a unique combination of required
  option args and position args

. avoid adding optional options to a cmd def that if
  used would make the command match a different cmd def

FIXME: record when repeated cmd defs are found so we can
avoid reporting them twice, e.g. once for A vs B and
second time for B vs A.
