Thoughts? Preference? Other ideas? thanks, grant ps. It's more obvious now that the return value from mmc_blk_issue_rq() is getting ignored. *sigh* -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
