Subject: [PATCH 1/7] Remove action device from LVM reject list
Because the device doesn't depend on itself the existing code
won't remove the device we are trying to modify from the list.

Subject: [PATCH 3/7] Switch LVM devices filter from "reject" to "accept" by
default
We currently use the LVM reject filter to filter out hidden and
ignored devices, this commit changes the behaviour to reject all
devices by default and accept only physical volumes that are not
hidden or ignored. This is preparation for the switch from the
existing lvm.conf based filtering to the new devices file based
filtering introduced in LVM 2.03.12 which allows only listing
"accepted" devices. This allows us to support both the "old" and
"new" style filtering using the same code.

Subject: [PATCH 5/7] Make sure PVs are added/deleted to/from the LVM device
file
We are using the --devices option when running LVM commands which
mean the newly created PV won't be added to the device list by
pvcreate so we need to do that manually.

Subject: [PATCH] iscsi: Replace all log_exception_info calls with log.info
We don't get any useful information from the exception, it's
always the same traceback from a failed DBus call and we only use
these when a called failed because firmware ISCSI is not supported.
The resulting log message also looks like a failure with the
traceback logged and not just as a debug information.
