Here is the thread of discussions which leads this series. https://lore.kernel.org/all/167019256481.3792653.4369637751468386073.stgit@devnote3/T/#u I agreed that NACK the taint flag itself, and I thought I need to update the function error injection so that the developers understand the requirements and carefully use the ALLOW_ERROR_INJECTION() macro. So I removed the confusing EI_ETYPE_NONE (this should not be there, use errno instead), and update the document about error injectable functions.
