Thinking about this a bit further I think a "give up" notification to a filesystem is an incremental addition to the common vfs layer invalidate_partition() and now unmap_partition(). Because "sync if you can, but give up quickly" is handled by fsync_bdev() and generic_make_request() returning immediate errors. It's only the file system triggered retries that we need to turn off. -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
