The quilt patch titled Subject: error-injection: remove EI_ETYPE_NONE has been removed from the -mm tree. Its filename was error-injection-remove-ei_etype_none.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Masami Hiramatsu (Google) <mhiramat@xxxxxxxxxx> Subject: error-injection: remove EI_ETYPE_NONE Date: Mon, 12 Dec 2022 11:46:44 +0900 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.
