Now that we have the mechanisms in here, allow shared memory in a
postcopy.
Note that QEMU can't tell who all the users of shared regions are
and thus can't tell whether all the users of the shared regions
have appropriate support for postcopy. Those devices that

The new option can be used to indicate that the file contents can
be destroyed and don't need to be flushed to disk when QEMU exits
or when the memory backend object is removed.
Internally, it will trigger a madvise(MADV_REMOVE) call when the
memory backend is removed.

Hi,
This is a RFC/WIP series that enables postcopy migration
with shared memory to a vhost-user process.
It's based off current-head + Alexey's bitmap series
It's tested with vhost-user-bridge and a dpdk (modified by Maxime
that will get posted separately) - both
This series adds a new "discard-data" option to
memory-backend-file. The new option will be useful if somebody
is sharing RAM contents on a pre-existing file using share=on,
but don't need data to be flushed to disk when QEMU exits.
Internally, it will trigger a madvise(MADV_REMOVE) call when the
UI stuff is remote desktop stuff (Spice, VNC) and input stuff (mouse,
keyboard).
