Subject: [PATCH qemu 34/39] drive-mirror: add support for sync=bitmap
mode=never
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds support for the "BITMAP" sync mode to drive-mirror and
blockdev-mirror. It adds support only for the BitmapSyncMode "never,"
because it's the simplest mode.
This mode simply uses a user-provided bitmap as an initial copy
manifest, and then does not clear any bits in the bitmap at the
conclusion of the operation.
Any new writes dirtied during the operation are copied out, in contrast
to backup. Note that whether these writes are reflected in the bitmap
at the conclusion of the operation depends on whether that bitmap is
actually recording!
This patch was originally based on one by Ma Haocong, but it has since
been modified pretty heavily.

Subject: [PATCH qemu 35/39] drive-mirror: add support for conditional and
always bitmap sync modes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Teach mirror two new tricks for using bitmaps:
Always: no matter what, we synchronize the copy_bitmap back to the
sync_bitmap. In effect, this allows us resume a failed mirror at a later
date.
Conditional: On success only, we sync the bitmap. This is akin to
incremental backup modes; we can use this bitmap to later refresh a
successfully created mirror.

Subject: [PATCH qemu 39/39] mirror: move some checks to qmp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
and assert the passing conditions in block/mirror.c. while incremental
mode was never available for drive-mirror, it makes the interface more
uniform w.r.t. backup block jobs.
