Merge patch series "alloc misaligned vectors for zoned XFS v2"

Christoph Hellwig <hch@lst.de> says:

This series enables the new block layer support for misaligned
individual vectors for zoned XFS.

The first patch is the from Qu and supposedly already applied to
the vfs iomap 6.19 branch, but I can't find it there.  The next
two are small fixups for it, and the last one makes use of this
new functionality in XFS.
