[PATCH v2 0/4] btrfs: allow creating inline data extents for sector size < page size case

[Qu Wenruo <wqu@suse.com>]

[CHANGELOG]
v2:
- Add the previous inline read fix into the series
- Add a patch to remove the subpage experimental warning message
  The main reason for the warning is the lack of some features, but it's
  no longer the case.

For btrfs block size < page size (subpage), there used to a list of
features that are not supported:

- RAID56
  Added in v5.19

- Block perfect compressed write
  Added in v6.13, previously only page aligned range can go through
  compressed write path.

- Inline data extent creation

But now the only feature that is missing is only inline data extent
creation.

And all technical problems are solved in v6.13, it's time for us to
allow subpage btrfs to create inline data extents.

The first patch is to fix a bug that can only be triggered with recent
partial uptodate folio support.

The second patch fixes a minor issue for qgroup accounting for inlined
data extents.

The third path enables inline data extent creation for subpage btrfs.

And finally remove the experimental warning message for subpage btrfs.

Qu Wenruo (4):
  btrfs: fix inline data extent reads which zero out the remaining part
  btrfs: fix the qgroup data free range for inline data extents
  btrfs: allow inline data extents creation if sector size < page size
  btrfs: remove the subpage related warning message
