The 6.0 kernel made some changes to the direct io interface to allow
offsets in user addresses. This based on the hardware's capabilities
reported in the request_queue's dma_alignment attribute.
dm-crypt, -log-writes and -integrity require direct io be aligned to the
block size
From: Keith Busch
This device mapper needs bio vectors to be sized and memory aligned to
the logical block size. Set the minimum required queue limit
accordingly.

Device mappers had always been getting the default 511 dma mask, but
the underlying device might have a larger alignment requirement. Since
this value is used to determine alloweable direct-io alignment, this
needs to be a stackable limit.
