It might not be too useful for nfs but Colin has a patchset spreading
the use of the freezable schedules in a number of places in an attempt
to reduce freeze latency for android, which includes introducing a lot
of schedule_*_freezable() constructs, so I think we need these
warnings one way or the other so that we don't end up with more
problems like nfs currently has.

Thakns.
