A logic has been introduced to skip hole in files and bdevs and so to copy only data. For files lseek is used, for bdevs new bdev API spdk_bdev_seek_[data,hole]. Show progress function will display only affected size_unit Signed-off-by: Damiano Cipriani <damiano.cipriani@suse.com> Change-Id: Ide2b0d825267603d45e00872ea719c8f0e82a60c Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/14363 Tested-by: SPDK CI Jenkins <sys_sgci@intel.com> Reviewed-by: Ben Walker <benjamin.walker@intel.com> Reviewed-by: Jim Harris <james.r.harris@intel.com>
