When the VM exits, we must call put_page() for every page referenced in the shadow TLB. Without this patch, we usually leak 30-50 host pages (120 - 200 KiB with 4 KiB pages). The maximum number of pages leaked is the size of our shadow TLB, 64 pages. Signed-off-by: Hollis Blanchard <hollisb@xxxxxxxxxx> --- The obvious question is "why didn't we see this before?" Basically, we'd never looked for it, and since most of our work was in the kernel we always ended up rebooting before exhausting host memory. Since it's such a large leak, and a simple fix, please commit this for 2.6.28. This patch does apply to kvm.git with fuzz, but if you prefer I can send a separate patch for that later.
Applied on both master and the 2.6.28 queue. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm-ppc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
