5680d14ecd Avoid 'mda inconsistency' by properly registering UNLABELLED_PV flag (2.02.86).
When a PV label write is deferred to a vg_write call (as introduced by a patch
in 2.02.86), the PV is flagged with the internal UNLABELLED_PV flag. However,
when calling vg_archive before vg_write, we still have the PV labelled with the
UNLABELLED_PV flag which was not recognised as a proper flag while exporting
VG metadata:

  # vgcreate vg /dev/sda
  No physical volume label read from /dev/sda
  Metadata inconsistency: Not all flags successfully exported.
  Metadata inconsistency: Not all flags successfully exported.
  Writing physical volume data to disk "/dev/sda"
  Physical volume "/dev/sda" successfully created
  Volume group "vg" successfully created

bf09a32006 Make dmsetup.static and lvm.static build when dmeventd is disabled.
udev may also need to be disabled if you didn't build it statically too.

dmeventd.static could be fixed with some more work but I don't really see the
point: without dlopen() it's useless, and if you have dlopen(), why not support
normal shared libraries too?

2ce5ca4375 Incomplete documentation is worse than no documentation.
Any documentation less-detailed than Documentation/device-mapper is
dangerous for the non-trivial ctr lines.  And anyway, this should be in s4
not here.

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.

39fc633957 Thin align volume size on chunk boundary size
If the extent_size is smaller then the chunk_size we may try
to find better aligment (wasting less space).

i.e. using  4KB extent_size and  64KB chunk size will
lead to creation of 64KB aligned thin volume.

after it - so we can support  lvcreate -an thin snapshot.

44190723a8 Correctly handle concurrent read (CR) locks in singlenode clvmd. This means
that we can also test clustered volume groups (vgcreate -c y) in the test
suite. Unfortunately we can't make this the testing default since cluster
mirrors require further infrastructure, and snapshots probably don't work at
all. I'll eventually add a few test cases that create clustered VGs
specifically.

267a575768 Thin removing limitation on activation of pool device.
Since activation of pool is now independent on thin activation,
user may do whatever he needs - thought preferable thin should stay alive,
but it it will be found inactivate, update_pool will bring the pool up.
