Please dint get me wrong .... but please take a look more carefully
Original code: ((e) == EIO || (e) == EILSEQ)
True for fatal errors, and false for non fatal ones
But function called td_NON_fatal_error()
And it should result opposite result
so my code: (!((e) == EIO || (e) == EILSEQ)) is equivalent of
(err != EIO) && (err != EILSEQ)
