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 introduces a new migration stat (zero-copy-copied)
that will be used to keep track of [*].
Honestly I would like some help with this naming, which I don't think
is quite good, but I could also not think on anything better.
The third patch keeps track of how many zero-copy flushes retured 1 [*]
