Ohh i ment to say that both errors are fatal, but function called
td_NON_fatal_error, and it result true in case of EIO or EILSEQ
this result continue_on_error logic broken because
io_u.c 1440:
if (icd->error && td_non_fatal_error(icd->error) &&
(td->o.continue_on_error & td_error_type(io_u->ddir,
icd->error))) {
/*
* If there is a non_fatal error, then add to the error
count
* and clear all the errors.
*/
update_error_count(td, icd->error);
td_clear_error(td);
icd->error = 0;
io_u->error = 0;
}
that's why i've inverted result.
FYI right after i've changed this my test which continuously hit ENOSPC
goes forward and provoke panic :)
