We can actually do this in the kernel. For small directories which could potentially get converted into htree format, we already sucking the entire directory and putting it into an rbtree. We could just do this for all directories less than or equal to 32k, but have them returned sorted by inode instead of by hash value. At least on my laptop, this accounts for 99.93% of the directories on my root filesystem. There are some fancy things that would have to be done to make telldir/seekdir, but the basic idea is pretty simple. - Ted -- 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
