For the record, there was another patch fixing a loop device issue https://patchwork.kernel.org/patch/1861831/ from Michael (CCed), that switched from LOOP_GET_STATUS to LOOP_GET_STATUS64, but afaics both types of the ioctl return at most 64 characters, so parsing /sys appears to be the way to go. david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
