I just tried your patch, and it seems to work VERY well. I just did a
make -j kernel compile while running netscape, and reading the linux-kernel
mailing list. My system load got so high that xload was completely black,
but everything worked, and mutt (my mail program) was only a bit sluggish.
This is on an AMD K6 200, 32 Megs ram, 64 Megs swap, with the perfect buffer
cache patch on top of pre-patch-2.0.31-2 and some IDE patches from Gadi Oxman.
This may really be the perfect buffer cache patch. No more thrashing
for swap when the system load goes balistic. Good work!
