Strictly speaking that's a backwards incompatible change, because
zeroes have never been and aren't enforced -- clients are free to fill
the remaining bits of ceph_osd_op with whatever values.
That said, the kernel client has always been zeroing the front portion
of the message before encoding, so even though the timeout field hasn't
been carried into ceph_osd_op definition in the kernel, it's always 0
(for "use osd_client_watch_timeout for this watch").
Thanks,
Ilya
