Do you really want to split the per-address-space pages list in

The main notables are the network fixes (uninitialized skb->dev could and
did cause oopses in ip_defrag) and the mm fixes (dirty pages without
mappings etc, causing problems in page_launder).
The mm cleanups also include removing "swapout()" as a VM operation, as

Hi Linus, Alan, Stephen,
the patch below implements trivial RSS ulimit enforcement
for the 2.4 kernel.
The hard limit (rlim_max) is enforced as a true hard limit,
both at page fault time and again from kswapd. The soft
limit is "enforced" by simply scanning and swapping the
process more

Probably.
There are some arguments for starting the writeout early, but there are
tons of arguments against it too (the main one being "avoid doing IO if
you can do so"),

Ok, page_launder is supposed to run

Please don't do this, it screws up the config option

Hi
I have try to activate APIC in my BIOS, but I didn't have this option.
Have you ever try it?

Hi - Here's another Oops from the same machine. It looks to be in a totally
different place in the code which probably means it's a memory problem? I'll
try installing on

No, that shouldn't be needed.
Look at the code-path: the kernel has the page locked, so nothing will
de-allocate the swap entry - so it's

Good catch. It should be ok to sleep for bdflush while holding the page,
but at the same time it's
