To try kztmem: 1) apply the monolithic patch to 2.6.36 2) rebuild your config ensuring that CONFIG_KZTMEM, CONFIG_CLEANCACHE, CONFIG_FRONTSWAP, and CONFIG_ZRAM (for xvMalloc) become enabled 3) rebuild and reboot with "kztmem" as a kernel boot parameter 4) see /sys/kernel/mm/kztmem/* for statistics... note that with lots of RAM and no swapping, little or no activity will be seen As I said, there are known weird bugs that may or may not show up in your configuration and build environment, so be prepared in advance that the kernel may crash... removing kztmem as a boot parameter should disable kztmem and result in a normal boot. Thanks in advance for trying and testing (and, if you are so inclined, debugging) kztmem! I'll be happy to answer any questions on- or off-list!
