Pedantically, the kernel is not implementing a RM as per some spec, it is using the TPM features to create isolation. Both sides can be argued. In this case, I think the patch to add a TPM response buffer in this one case is reasonable, and does not look so complicated that it is dangerous in the kernel. However the kernel will continue to return errnos in various cases, and a userspace that cannot handle them is kinda broken :) Jason
