Subject: [Qemu-devel] [PATCH v11 0/2] mirror: Improve zero write and discard
Date: Wed, 3 Feb 2016 09:52:19 +0800 [thread overview]
Message-ID: <1454464341-9494-1-git-send-email-famz@redhat.com> (raw)
v11: Rebase. The only difference is the "file" parameter of
bdrv_get_block_status_above.
Patch 1 rewrites mirror_iteration. Patch 2 is a small DRY cleaning up.
The main benefit is copying unallocated sectors (both zeroed and discarded)
doesn't go through the iov setup loop, as they don't need it.
Fam Zheng (2):
mirror: Rewrite mirror_iteration
mirror: Add mirror_wait_for_io
