zoned xfs updates

zoned xfs updates

[Christoph Hellwig]

Hi Carlos,

this series has a fix for an hamrless issue in a recent commit,
a cleanup, and then drops the experimental tag for the zoned
allocator now that it has been in an upstream release for a year.

[PATCH 1/3] xfs: drop the RTG reference later in xfs_ioc_rtgroup_geometry

[Christoph Hellwig]

Keep the rtgroup reference until after reporting the write pointer, as
that uses it.  Right now this is not a major issue as we don't support
shrinking file systems in a way that makes RTGs go away, but let's stick
to the proper reference counting to prepare for that.

[PATCH 2/3] xfs: factor rtgroup geom write pointer reporting into a helper

[Christoph Hellwig]

Sticks out a bit better if we add a separate helper for it.

[PATCH 3/3] xfs: drop the experimental warning for the zoned allocator

[Christoph Hellwig]

The zoned allocator has been released with 6.15 on May 25, 2025.  It has
seen constant maintenance and improvements and no major issues, so
promote it out of the experimental category.

Do we want to compact the numbering and change this to 19 ?

I'd agree with Christoph and not reuse the warn number but perhaps I'm
just being overly cautious as we don't have a 'stable' version which
zoned support would be backported to :P
