Since this is broken down nicely, a line or two about what each patch
does or doesn't address would be useful. In particular, having just
gotten a working RSS I'm suspicious of the patch named vm-no-rss-limit
being desirable ;-)
The bug with the RSS limit patch is that I forgot to
change the exec() code, so when init is exec()d it
gets an RSS limit of zero, which is inherited by all
its children --> always over the RSS limit, no page
aging, etc.
I need to find the cleanest way to add the inheriting
of RSS limit at exec time and send a patchlet for that
to akpm...
Thank you! I had assumed that the info was being carried through exec,
fork, and pthread_* and similar, and just not enforced.
I still think this will be great for those applications known to
occasionally get a tough data set and not converge or recurse beyond all
sense.
