So are you trying to say that you wrote this patch? Or that you think it does "the right thing" in which case it should be "Acked-by" or "Reviewed-by": https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/SubmittingPatches?id=f6f94e2ab1b33f0082ac22d71f66385a60d8157f#n297 Alex

At the moment the size of the buffer is set to 64K which is enough for approximately 150 VCPUs which is not the limit. This increases the buffer up to 256K which allows having a tree for approximately 600 VCPUs which is way beyond the real number we need. As only the real size of the tree is copied to the guest, there will be no impact on existing configurations.
