6ff65e6755 vdo: check_point_frequence is unused option
This vdo parameter existed in the early stage of integration of vdo into lvm2,
but later it's been removed from vdoformat tool - so actually if
there would be any non-zero value it would cause error on lvcreate.
Option was not stored on disk in lvm2 metadata.

Remove this vdo parameter from lvm2 sources.

(Although this vdo parameter will be still accepted on cmdline through
 --vdosettings option, but it will be ignored.)

74feebdab7 device_id: fix handling of non-PV with duplicate serial number
Fix in the code that matches devices to system.devices entries when
the devices have the same serial number.  A non-PV device in
system.devices has no pvid value, and the code was segfaulting
when checking the null pvid value.

4cdb178968 device_id: ignore trailing underscores in t10 wwid from devices file
In previous lvm versions, trailing spaces at the end of a t10 wwid would
be replaced with underscores, so the IDNAME string in system.devices
would look something like "t10.123_".  Current versions of lvm ignore
trailing spaces in a t10 wwid, so the IDNAME string used would be
"t10.123".  The different values would cause lvm to not recognize a
device in system.devices with the trailing _.  Fix this by ignoring
trailing underscores in the IDNAME string from system.devices.

24e4b6df11 tests: integrity-caching: ensure raid redundancy
The recent fix 05c2b10c5d ensures that raid LV images are not
using the same devices.  This was happening in the lvextend commands
used by this test, so fix the test to use more devices to ensue
redundancy.

05c2b10c5d Fix "multisegment RAID1, allocator uses one disk for both legs"
In case of e.g. 3 PVs, creating or extending a RaidLV causes SubLV
collocation thus putting segments of diffent rimage (and potentially
larger rmeta) SubLVs onto the same PV.  For redundant RaidLVs this'll
compromise redundancy.  Fix by detecting such bogus allocation on
lvcreate/lvextend and reject the request.

368381fd40 lvreduce: make _lvseg_get_stripes handle integrity layer
lvreduce uses _lvseg_get_stripes() which was unable to get raid stripe
info with an integrity layer present.  This caused lvreduce on a
raid+integrity LV to fail prematurely when checking stripe parameters.
An unhelpful error message about stripe size would be printed.

6d262eaf64 lvmcache: fix valgrind error when dropping md duplicate
When lvmcache info is dropped because it's an md component,
then the lvmcache vginfo can also be dropped, but the list
iterator was still using the list head in vginfo, so break
from the loop earlier to avoid it.

8947964f10 wipe_lv: use zeroing ioctl only for large sizes
There is no easy way to detect, whether device supports zeroing,
and kernel also zeroes device when it's not directly supported,
but with extra message:

operation not supported error, dev X, sector Y op 0x9:(WRITE_ZEROES)...

So to avoid generating such message with every 'lvcreate', use for
zeroing of upto 8K just standard write of zeroed page.
(maybe we can go with even larger sizes).

e8e6347ba3 vdo: use fixed size vdopool wrapper
Instead of using size of 'empty header' in vdopool use fixed size 4K
for a 'wrappeing' vdo-pool device.

This fixes the issue when user tried to activate vdo-pool after
a conversion from vdo managed device with 'vgchange -ay' - where
this command activated all LVs with 'vdo-pool' wrapping device as well,
but this converted pool uses  0-length header.

This 4k size should usually prevent other tools like 'blkid' recognize
such device as anything - so it shouldn't cause any problems with
duplicate indentification of devices.

69ea2e3f94 vg_read: keep MISSING_PV when device with no mda reappears
Remove old code that became incorrect at some point.
It's probably a fragment of an old condition that was left
behind because it wasn't understood.  We don't want to drop
the MISSING_PV flag just because the PV has no mda in use.
The device that was missing may have stale data, so the user
needs to decide if the device should be removed or restored.

1857eb9fe0 lvresize: fix check for mounted and renamed LV to handle spaces
Replace spaces with \040 in directory paths from getmntent (mtab).

The recent commit 5374a44c57 compares mount point directory paths
from /etc/mtab and /proc/mounts, in order to detect when a mounted
LV has been renamed.  The directory path comparison does not work
correctly when the path contains spaces because getmntent uses
ascii space chars and proc replaces spaces with \040.

c9fdc828ff vgchange autoactivation: skip regex filter containing symlinks
"vgchange -aay --autoactivation event" is called by our udev rule.
When the udev rule runs, symlinks for devices may not all be created
yet.  If the regex filter contains symlinks, it won't work correctly.
This command uses devices that already passed through pvscan.  Since
pvscan applies the regex filter correctly, this command inherits the
filtering from pvscan and can skip the regex filter itself.

See the previous commit

17a3585cbb pvscan: use alternate device names from DEVLINKS to check filter
pvscan --cache <dev> is called by our udev rule at a time when all
the symlinks for <dev> may not be created yet (by other udev rules.)
The regex filter in lvm.conf may refer to <dev> using a symlink name
that hasn't yet been created, which would cause <dev> to not match
the filter regex.  The DEVLINKS env var, set by udev, contains all
the symlink names for <dev> that have been or will be created.
So, we add all these symlink names to dev->aliases, as if we had
found them in /dev.  This allows <dev> to be recognized by a regex
filter containing a symlink for <dev>.
