SubjectPriorities of kswapd & bdflush
Hi!

kswapd has realtime priority. Well, I do not like it (it likes to loop
forever), but it is probably neccessary.

Bdflush does not have realtime priority. So if kswapd goes crazy,
bdflush is defunct. Bdflush may like realtime priority, too: it acts
only if kernel is too full with unsaved data - at that time, you want
both to swap _and_ to flush dirty buffers back.

Anyway, at least when emergency sync is requested, bdflush should get
realtime priority. As I said, it might be good thing (tm) for bdflush
to have realtime priority all the time...

What do you think?
