A good article on it is at LWN: http://lwn.net/Articles/329458/

It's available in Ubuntu, at least the newer ones, it didn't work with
Hardy/8.04 because the kernel wasn't new enough.

It's something I found while searching for a way to estimate our
requirements prior to the VPS migration.  We had 2GB of RAM and running top
and meminfo just didn't give me useful numbers for how much RAM we really
needed.  smem helped me figure out that if I started tweaking things by
running nginx and not running clamav, and perhaps spamassassin, we could
probably get by with 512MB.

I wanted to go with Linode 1024, but didn't want to spend that much per
month ($40) when the ad revenue we get has been as low as $60 a month.  Then
I found Tektonic had the 10% off for life so it came to $25.20 a month and
used a small 256MB slice at Prgmr for DNS, that comes out to $6.40 a month
paying for a year.  I have since found a free secondary DNS provider that I
think I'll be happy with, so with a 1024MB slice at Prgmr slice it will be
$20 a month paying per month, or $16 a month paying for the year, or $28.80
a month with 2048MB paying by year.
