[gnbd-kernel] bz 442606: Switch gnbd to use deadline scheduler by default.
GNBD was hanging under load with O_DIRECT. GNBD needs to block in its
request function. This causes some problems with the anticipatory scheduler,
which GNBD was using by default. To avoid these, this fix makes gnbd use the
deadline scheduler by default.
