d50c6d4bf5 Add new --sysinit option for vgchange and lvchange.
A shortcut for --ignorelockingfailure, --ignoremonitoring, --poll n options
and LVM_SUPPRESS_LOCKING_FAILURE_MESSAGES environment variable used all at
once in initialisation scripts (e.g. rc.sysinit or initrd).

180b3dea11 Install plugins to subdirs
Target install_dm_plugin installs files to libdir/device-mapper.
Target install_lvm2_plugin installs files to libdir/lvm2.

Both targets creates relative links to libdir to keep the code
compatible with current dlopen handling.

Once we will be able to read plugins from subdir, links
could be removed.

e92d87cef6 Synchronize "remove" dm task while reverting unsuccessful "create" dm task
(with table provided).

This remove ioctl generates udev events like any other hence it needs to be
synchronized properly as well. Also, add dm task type in debug log when
setting a cookie (for better debugging).

d6b9d2cbc3 Add a "should" alongside "not" to the test utilities. When a "should" command
fails, the test will carry on but will issue a warning. The harness detects
such warnings from tests and marks tests that passed with warnings with a
special status.

5ff4274f9b Don't run any complex initialisation for the "version" lvm2 command.
We can use it even in read-only environment where a try to initialise
file-based locking fails (not to mention other processing related with
lvm2 init). Simply, we want to output the version only, nothing else.
And this should always work.

6c6ce2ba0e Test all combinations of mirror conversion, both while the LV
is active and while it is in-active.

+for i in $(seq 0 4); do
+       for j in $(seq 0 4); do
+               for k in core disk mirrored; do
+                       for l in core disk mirrored; do

The testing code still needs some improvement.  I'd like to add
the ability to test specifying the PVs to be added/removed during
a convert.  It will also be important to test partial PV
specification during down converts (i.e. request to remove more
mirror images than we have provided PVs for).

942d6ef29f Add support for new IMPORT{db} udev rule.
This rule appeared in udev v152 and it helps us to support spurious events
where we didn't have any flags set (events originated in udevadm trigger
or the watch rule). These flags are important to direct the rule application.
Now, with the help of this rule, we can regenerate old udev db content.
To implement this correctly, we need to flag all proper DM udev events with
DM_UDEV_PRIMARY_SOURCE_FLAG. That happens automatically for all ioctls
generating events originated in libdevmapper.

d7c9d72390 Patch to fix bug 586021 and mantain historical behavior of
being able to remove more images from a mirror than the
number of PVs directly specified for removal.

The effort to fix bug 581611 corrected a bug that was unnoticed
at the time.  The loop in _remove_mirror_images that looks over
the specified PVs was allowing devices that were previously
counted and moved to the end of the list to be double-counted.
This resulted in the number of devices needed for removal always
being satisfied - even if the user did not specify enough PVs
for removal to satisfy the request.  When 581611 was fixed, this
double-counting no longer took place and the result was to remove
only the minimum of the number of PVs specified or the number
that was asked to be removed.

By simply always setting 'new_area_count' (as used to be done
only in the else statement), we return to the previous behavior.
Indeed, this is exactly what the double-counting was allowing
to happen before the fix of 581611.

60267bdce8 Disallow the direct removal of a merging snapshot.
Allow lv_remove_with_dependencies() to know the top-level LV that was
requested to be removed (otherwise it recurses and we lose context).

A merging snapshot cannot be removed directly but the associated origin
can be.  Disallow removal of a merging snapshot unless the associated
origin is also being removed.

d6d08486c8 Remove redundant check in _lvs_single now that the caller
(process_each_lv_in_vg) provides it.

Also, removing this check from _lvs_single now allows displaying hidden
LVs that are specifically named on the command line.

6ddb5ecd72 Set appropriate udev flags for reserved LVs.
There's no need for foreign udev rules to touch LVM reserved devices
(snapshot, pvmove, _mlog, _mimage, _vorigin) even if they happen to
be visible. The same applies for /dev/disk content - no need to create
any content for these devices (and so no need to run any "blkid" etc.).
This also prevents setting any inotify "watch" from udev rules on such
devices that is a source of race conditions (the rules need to honor
DM_UDEV_DISABLE_OTHER_RULES_FLAG for this to work though).

6753ff894f The following tests in the testsuite have race conditions:
1) Test that the primary mirror image cannot be removed while
   the mirror set is sync'ing.
2) Test that you cannot start a second mirror up-convert while
   one is already in progress.

The trouble is that if the sync/conversion finishes before the
tests occur, the tests will fail by why of success where there
should have been failure.  This means the sync/conversion must
happen very quickly, but this is possible because the test
mirrors we are creating are so small.

In order to decrease the likelyhood of these test failing (or
more correctly, failing to test the right thing), I've increase
the size of the mirrors.  It will still be remotely possible that
the tests will fail (by way of failing to test the right thing).
If this continues to happen, more involved mechanisms will need
to be put in place.  (Perhaps these will still be created, but
this change should be a remedy until that time.)
