Hi, I noticed yesterday that a write to fallocate space via directIO results in fallback to buffer_IO. ie the userspace pages get copied to the page cache and then call a sync. I guess this defeat the purpose of using directIO. May be we should consider this a high priority bug. -aneesh -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
