I developed new exiting stuff this afternoon! The most important thing is
the swapout smart weight code. Basing the priority on the number of
process to try to swapout was really ugly and not smart.
The second change is done over shrink_mmap(), this will cause
shrink_mmap() to care very more about aging. We have only one bit and we
must use it carefully to get not out of cache ;)
I also added/removed some PG_referenced. But please, don't trust too much
the pg_refernced changes since I have not thought about it too much (maybe
they are not needed?).
I returned to put the minimum of cache and buffer to 5%. This allow me to
run every trashing memory proggy I can for every time but I still have all
my last command run (free) and filesystem (ls -l) in cache (because the
trashing memory _only_ play with its VM and asks nothing to the kernel of
course).
Ah and woops, in the last patch I do a mistake and I forget to change
max_cnt to unsigned long. This should be changed also in your tree, Linus.
This new patch seems to really rocks here and seems _far_ better than
anything I tried before! Steve, could try it and feedback? Thanks ;)
Please excuse me Linus if I have not yet cleanedup things, but my spare
time is very small and I would _try_ to improve things a bit more
before...
This patch is against 2.2.0-pre4 (the lateest patch posted by Linus here).
