Subject: Re: [RFC PATCH v5 0/4] add simple copy support

Dave,

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 is possible to extend
to cross device XCOPY in future.

Thanks,
Selva
