Hi all,

Things are looking better and better :-)
Running with SCHED_FIFO now gives most interrupt to process
latencies below 3 ms !!!
(streaming 1.5 times RAM; read, write, copy tested)

But there are some, nowadays very few, spikes that hurts...
Worst is above 100 ms

But in this kernel does not have the loop limits in shrink_mmap
