since beginning, it is actually added by commit d690cb8ae14b in

If max segment size isn't aligned with virt_boundary_mask,
bio_split_rw()
will split the bio with max segment size, this way still works, just
not
efficiently. And in reality, the two are often aligned.
I take it as a compliment, building exotic configurations is something
I'd love to be good at.
But, as far as I understand, this warning is caused by my raid config,
right?
How is it possible that a raid6 array has a queue/max_segment_size of
(2^16 - 1) in sysfs while 2 others on the same system have a
queue/max_segment_size of (2^32 - 1)?
they are all rotational devices on the same SAS controller, just this
malfunctioning one uses SATA drives while the other 2 are SAS.
Understanding this would help me to avoid this unwanted behavior.
