Subject: [PATCH] Fix getting PV info in LVMPhysicalVolume from the cache
"self.device" is string for formats so accessing "self.device.path"
results in an AttributeError.

Subject: [PATCH] Do not crash when changing disklabel on disks with active
devices
The _find_active_devices_on_action_disks function originally
prevented from making any changes on disks with active devices
(active LVs, mounted partitions etc.) This was changed in
b72e957d2b23444824316331ae21d1c594371e9c and the check currently
prevents only reformatting the disklabel on such disks which
should be already impossible on disks with an existing partition.
This change for the 3.4 stable branch keeps the current behaviour
where the active devices are teared down when running in installer
mode to avoid potential issues with the installer.

Subject: [PATCH] ActionDestroyDevice should not obsolete ActionRemoveMember
If we want to remove a PV from a VG and then remove the PV device,
the ActionDestroyDevice must not obsolete the ActionRemoveMember
action. Eventhough we are going to remove the device, we still
need to call "vgreduce" first.

Subject: [PATCH 4/4] Add option to attach a newly created cache pool to
existing LV
Because we do not have action for attaching the cache pool, we
cannot schedule both adding the fast PV to the VG and attaching
the cache pool to existing LV. This hack allows to schedule the
attach to happen after the cache pool is created.

We are using "real" disk names ("sda", "sdb"...) in this test so
we need to avoid reading their real sizes which we do for existing
devices using os.stat. The test can fail if we have a disk with
the same name and small (or zero) size.

Subject: [PATCH 1/8] Fix removing zFCP SCSI devices
Values parsed from /proc/scsi/scsi were not correctly used to assemble
paths to SCSI devices.
For example:
/sys/bus/scsi/devices/0:0:00:00/
was incorrectly accessed instead of:
/sys/bus/scsi/devices/0:0:0:0/
Switch to a more reliable way of listing the available SCSI devices.

Subject: [PATCH 4/8] Allow to delete more than one SCSI device
NPIV zFCP devices can attach more than one SCSI device, so allow to
delete them all. For non-NPIV devices it means possible slowdown, since
all SCSI devices would now be checked.

Subject: [PATCH 2/3] Do not read DDF RAID UUID from udev
The UUID we get from udev isn't the array UUID, we need to get
that using libblockdev.

Subject: [PATCH 3/3] Do not crash when a disk populator doesn't return kwargs
This happens when trying to use Blivet on a system with a BIOS
RAID without dmraid installed. Because we don't fully support
BIOS RAIDs using MD the MDBiosRaidDevicePopulator helper fails
to get kwargs for the BIOS RAID "disk" and populate fails.
