[Qemu-devel] [PATCH 0/2] backup: Use copy offloading

Posted by Fam Zheng 7 years, 5 months ago

Based-on: <20180529055959.32002-1-famz@redhat.com>
([PATCH v7 00/10] qemu-img convert with copy offloading)

This enhances the backup job to make use of the copy offloading API. It
eliminates the necessity to use the bounce buffer as well as speeding up the
copy operation when the backend supports it.
