Subject: Kernel call chain search tool?
Date: Tue, 24 Sep 2002 21:36:40 -0700 [thread overview]
Message-ID: <3D913D58.49D855DB@kegel.com> (raw)
<prelude>
I have a large multithreaded program that has a habit of using too
much memory, and as a safeguard, I want to kill it before it makes
the system unstable. The OOM killer often guesses wrong, and RLIMIT_AS
kills too soon because of the address space used up by the many thread
stacks.
So I'd like an RLIMIT_RSS that just kills the fat process.
There have been a couple patches to implement RLIMIT_RSS, e.g.
Peter Chubb's
http://marc.theaimsgroup.com/?l=linux-kernel&m=97892951101598&w=2
and the two from Rik, all of which are too complex for my needs
(and which only swap out instead of kill), so I guess I have to roll my
own.
</prelude>
Rik's patch checks rss in handle_mm_fault(); Peter's
checked it in do_swap_page() and do_anonymous_page().
As a kernel newbie, I don't have a feel for how
those calls relate to each other. Is there a tool
somewhere that will take a set of function names and
list all the kernel call chains that start in one of
the functions and end in another?
