You could try instrumenting the paths in bdflush and kswapd, to see
what really happens when they run crazy. This would help a lot.
:-( My knowledge of the kernel is too poor and I have too few time to
study it.
I tried the suggestion of A.Arcangeli about size interval. The test is
always
Hi!
I found the time to make some tests with 2.4 and the blk-13B patch.
It performs very well, no process starvation, no missed merges,
etc., but sometimes it happens dbflush and kswapd start eating
100% CPU for about 20-30 secs.:
11:02am up 18 min, 5 users, load average: 2.74, 1.97, 1.15
When will the powerpc tree be merged ? Neither the
official 2.4 nor the -ac8 work. They don't even compile.
Bye.

2.2.18, SMP.
It seems that anything I write in /proc/sys/vm/bdflush does not make
any difference. Metadata is always flushed every 5 seconds.

How to crash kernel 2.2.17-18:
Turn on the USB printer without paper and try
to print something. Wait for the "printer.c: usblp0:
out of paper" message and turn off the printer.
Ok, now "killall gs" will freeze the system.
(kernel 2.2.17-18, I did't try 2.4, GCC 2.95.3, PowerPC750)

There are 3 ways: 1- dropping packets (obvious), 2- buffer packets and delay

Yes, but if the queue is short processes are likely to remain
blocked in D state for more time and the chances to merge rq
are smaller.
IMHO we should add a way to give priority to rqs from
