Can't free the ramdisk (initrd, pivot_root)
On the same topic, I have not found any change in free memory reported before and after the ioctl call. Though umount /initrd does free around 2 MB.

With Scott's patch applied, I get substantially better performance on low-memory machines, so I'm guessing it's doing its job. Also, just umount /initrd for me made it still possible to mount it, so it clearly did not go away.

I can't take credit for the patch, just the (mis)fortune of having to track down its existence. :) All mentions of it in Alan's older change logs have it uncredited, so I'm unsure if he or someone else fixed it.
