I like the idea of this patch. It could be a long term solution. If we can calculate the size of available variables by ourselves, we don't need to call QueryVariableInfo(). It makes efivars robust against buggy firmwares. Also, this patch actually fixes a serious bug, failing boot up. In theory, QueryVariableInfo() should return accurate values to kernel. But, it doesn't in practice. I think creating blacklist will be like playing whac-a-mole, because we can't anticipate how many buggy firmwares will appear in the future.
