But with this "fix" you'd be adding another one in the process.
Admitted, it's only a performance bug, but I found it to grind the machine to an absolute halt when doing IO intensive stuff or running large programs...
Stephen Tweedie, Andrea Arcangeli and me have been looking at this bug and others and have found there's pretty much NO WAY to fix this without some bigger changes in the VM code. Performance will suck in the earlier 2.4 kernels, but I hope to have some new VM code ready later on for a more readable, better maintainable, more stable VM subsystem with somewhat higher performance.
(I should write down the design we made at OLS and will do so shortly)
