Patch series "error-injection: Clarify the requirements of error
injectable functions".
Patches for clarifying the requirement of error injectable functions and
to remove the confusing EI_ETYPE_NONE.
This patch (of 2):
Since the EI_ETYPE_NONE is confusing type, replace it with appropriate
errno. The EI_ETYPE_NONE has been introduced for a dummy (error) value,
but it can mislead people that they can use ALLOW_ERROR_INJECTION(func,
NONE). So remove it from the EI_ETYPE and use appropriate errno instead.
[akpm@linux-foundation.org: include/linux/error-injection.h needs errno.h]
