bch_writeback_thread() is calling try_to_freeze(), but that's just an 
expensive no-op given the fact that the thread is not marked freezable.

I/O helper kthreads, exactly such as the bcache writeback thread, actually 
shouldn't be freezable, because they are potentially necessary for 
finalizing the image write-out.

Let's send a friendly ping on these three patches after two weeks...

After a month, I think, it's time for another ping.
