Hi Jens,

Now that we are on the other side of the merge window: do you perhaps
want Pankaj to repost this patch series? From what I have heard in
several fora (JEDEC, SNIA) all flash storage vendors except one (WDC)
are in favor of a contiguous LBA space and hence are in favor of
supporting zone sizes that are not a power of two.

As you may know in JEDEC we are working on standardizing zoned storage
for UFS devices. We (JEDEC JC-64.1 committee members) would like to know
whether or not we should require that the UFS zone size should be a
power of two.

Thank you,

Bart.
