[PATCH 0/3] fio: Avoid errno and errno string mismatch

Hello all,

This series fixes a problem where errno and error string representing that
errno could be out of sync.

Another possible solution is to remove td->verror everywhere and make sure
that the function wants the error string calls strerror() with the errno
when they actually need it. However, that would be a larger change.

Another optimization that could also be done is to look at the places where
we call update_error_count() and td_clear_error(), if we don't set
td->error for a non-fatal error, there is no reason to unconditionally call
td_clear_error() for a non-fatal error. (update_error_count() still has to
be called, as it sets td->first_error.) However, I do not really understand
why update_error_count() + td_clear_error() is called by both:
io_u.c:io_completed() and backend.c:break_on_this_error(), so I avoided to
do this optimization.
