I've put out arca-vm-9.
It seems that it's a lose marking as not referenced all freed pages in
__free_pages(). Probably because shrink_mmap() doesn't like to decrease
the `count' on just freed pages. So now I mark all freed pages as
referenced.
In the last patches (arca-vm[78] I forgot to include the filemap.c diff)
that seems to improve performances here (allowing the swap cache to be
shrunk without care about pgcache_under_min()).
arca-vm-9 return to a linear behavior in cacluating the swapout weight.
You can donwload arca-vm-9 from here:
ftp://e-mind.com/pub/linux/kernel-patches/2.2.0-pre4-arca-VM-9
Let me know if you'll try it. Thanks!
