Partition Alignment


As I stated in my first post, I have recently received a Dragonboard 820c with Debian installed with the following kernel:
Linux version 4.11.0-qcomlt (abuild@r2-a19) (gcc version 7.2.1 20171025 (Debian 7.2.0-12) ) #1 SMP PREEMPT Mon Nov 6 23:24:36 UTC 2017
LXQt 0.11.1
root@linaro-alip:~# cat /etc/debian_version

On my actual hardware, lsblk reports, for each partition:
PHY-SEC = LOG-SEC = 4096 == 1 block
MIN-IO = OPT-IO = 65536 = 16 blocks
ALIGNMENT = (16 - StartingLBA mod 16) mod 16 blocks
ALIGNMENT is zero for sti but not for any other partition, in particular, for persist, userdata, cache and system, which would be expected to hold filesystems.
Is it the case that this no longer matters as the kernel driver or UFS controller takes care of alignment issues?

Again, on the actual hardware, last_parti, at /dev/sdd4, /dev/sde33 and /dev/sdf4, has zero sectors as reported by:
root@linaro-alip:~# fdisk -l -o Device,Start,End,Sectors,Type,Attrs,Name
with the preceding partition taking the remainder of the LU.
Does the patch.xml in dragonboard-820c-bootloader-ufs-linux-31 rectify this? It appears to intend to do so.
Is there any documentation on the xml tag attributes? In particular, what is bHighPriorityLUN?
