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.
