As far as I remember at OLS we decided to implement per-zone RLU

It's there in the TODO list. It is easy to implement. I can do that
in the next revision. We are re-using the LRU lock, since the
isolate_pages callback is called under the zone's LRU lock.
Separate limits for RSS and RSS+pagecache are also a must.
I remember that we discussed having one limit, but we can come up
with a configuration parameter to do it. I'll do that in the
next release.
BTW, if you send smb. else's patches you may include a 'From: xxx'
line into the letter to address the original author.
I'll do that for the res_counters_infra patch. Although I had used
res_counter, the hooks in mm_struct earlier (http://lkml.org/lkml/2007/2/19/12).
A lot of the code for the reclaim logic and the meta_page is yours.
Please do identify patches where you would like to see your
signed-off-by and where you think the entire patch is completely
yours.
