[PATCH 0/6] ZNS: Extra features for current patches

[Javier González]

From: Javier González <javier.gonz at samsung.com>

This patchset extends zoned device functionality on top of the existing
v3 ZNS patchset that Keith sent last week.

Patches 1-5 are zoned block interface and IOCTL additions to expose ZNS
values to user-space. One major change is the addition of a new zone
management IOCTL that allows to extend zone management commands with
flags. I recall a conversation in the mailing list from early this year
where a similar approach was proposed by Matias, but never made it
upstream. We extended the IOCTL here to align with the comments in that
thread. Here, we are happy to get sign-offs by anyone that contributed
to the thread - just comment here or on the patch.

Patch 6 is nvme-only and adds an extra check to the ZNS report code to
ensure consistency on the zone count.

The patches apply on top of Jens' block-5.8 + Keith's V3 ZNS patches.

Thanks,
Javier
