Linus Torvalds has released a one-liner fix to the 2.2.4 kernel, which contains a bug that might cause problems on heavily loaded servers.

Linus writes:

There's a potential problem under certain load conditions with 2.2.4, which should be fixed by this one-liner. If you have trouble with 2.2.4 (apart from the obvious one where you have to add ", NULL" to two places in kernel/acct.c), would you try this simple thing?

Note that I _really_ want to hear about if if this makes any difference at all. It's a real bug, but I think it needs some rather pathological usage patterns to actually become a real problem. So I'd like to know if it actually makes a difference in real life...
