The first patch avoid spuriously returning 1 [*] when zero-copy flush is
attempted before any buffer was sent using MSG_ZEROCOPY.
[*] zero-copy not being used, even though it's enabled and supported
by kernel
The second patch should be applied on top of Juan Quintela's patchset that
reduces the frequency of multifd syncs, or else it could potentially send
20 warnings per second.
