Merge patch series "scsi: target: Add WRITE_ATOMIC_16 support"
John Garry <john.g.garry@oracle.com> says:
This is a reposting of Mike's atomic writes support for the SCSI
target.
Again, we are now only supporting target_core_iblock. It's implemented
similar to UNMAP where we do not do any emulation and instead pass the
operation to the block layer.
