I agree with you. Will remove BLKDEV_COPY_NOEMULATION.

Initially I started moving the dm-kcopyd interface to the block layer
as a generic interface.
Once I dig deeper in dm-kcopyd code, I figured that dm-kcopyd is
tightly coupled with dm_io()
To move dm-kcopyd to block layer, it would also require dm_io code to
be moved to block layer.
It would cause

copy_file_range() is work under progress. FALLOC_FL_UNSHARE of fallocate()
use case sounds interesting. I will try to address both of them in the
next series.
Adding SCSI_XCOPY() support is not in the scope of this patchset. However
blkdev_issue_copy() interface is made generic so that it

Matthew,
Maximum Source Range Count (MSRC) is limited by u8. So the maximum
number of source ranges is 256 (0 base value). The number of pages
required to be sent to the device is at most 2. Since we are
allocating the memory using kmalloc_array(), we would get a continuous
physical segment.

Thanks for reporting the memory leak. Will add a fix.
