Hi,
here's one more patch that we'd like to get to 5.12 before release, it's
changing where and how the superblock is stored in the zoned mode. It is
an on-disk format change but so far there are no implications for users
as the proper mkfs support hasn't been merged and is waiting for the
kernel side to settle.
Until now, the superblocks were derived from the zone index, but zone
size can differ per device. This is changed to be based on fixed offset
values, to make it independent of the device zone size.
The work on that got a bit delayed, we discussed the exact locations to
support potential device sizes and usecases. (Partially delayed also due
to my vacation.) Having that in the same release where the zoned mode is
declared usable is highly desired, there are userspace projects that
need to be updated to recognize the feature. Pushing that to the next
release would make things harder to test.
Please pull, thanks.
