Hi all,

this series fixes a minor and slightly less minor problem in the btrfs
zoned device code.  Note that for the second patch the comment might
not be correct any more - AFAICS 5.18 added support for the dup
profile for zoned devices, which means we do have a real issue now
if different devices have different hardware limitations.  I think we'll
need some code to check that all zoned devices have the exact same
hardware limits (max_sectors, max_segments, max_segment_size,
queue_boundary, virt_boundary), but I don't know the code well enough
to implement that myself

Found by code inspection as part of my bio cleanups.
