Why not? Note that NVMe TP4098 MAM support (not public yet I think so
I'm not going into details) is outside of scope as the current
RWF_ATOMIC requirements specifically require natural alignment and for
the writes to be between  stx_atomic_write_unit_min (LBA format) and
stx_atomic_write_unit_max (AWUPF) -- why are we not getting sequence
numbers right? Is that a SCSI issue?
