[linux-audio-user] Tuning pdflush?

Hi all,
    I recently switched to FC2 with the CCRMA 2.6.8 kernel. I was 
wondering if there is a way to tune pdflush in the 2.6 kernel like you 
could bdflush in the 2.4 kernel? I have seen advice on this list to set 
bdflush by adding *"echo* "10 64 0 0 2000 15000 90 5 0" > 
/proc/sys/vm/*bdflush" to the rc.local file, thus causing bdflush to 
write smaller chunks more often to disk instead of waiting for the 
"dirty buffer" to accumulate alot of stuff to write to disk all at once, 
possibly causing dropouts. Is there a way to do this with pdflush or is 
it even necessary with the 2.6 kernel? Thanks in advance.
