Hi,

Here is the 2nd version of the series to clarify the requirement of error
injectable functions and remove confusing EI_ETYPE_NONE.

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.

Thank you,
