Thanks, applied, although I simplified the patch a little:
@@ -3106,6 +3106,8 @@ _("Warning: The journal is dirty. You may wish to replay the journal like:\n\n"
com_err("tune2fs", retval,
"while recovering journal.\n");
printf(_("Please run e2fsck -fy %s.\n"), argv[1]);
+ if (!fs)
+ exit(1);
rc = 1;
goto closefs;
}
