Just to make this clear, any unindexed directory which is only one
block long and which then is extended to be greater than one block
will be indexed.  However, an unindexed directory which is already
larger than one block will always remain unindexed by the kernel ---
it requires userspace assistance to sort all of the directory entries
and index the directory in this case.

In general e2fsck -Df is all that's necessary.  The -y option isn't
really needed unless there is some filesystem corruption that you wish
to forcibly fix without asking your permission first.
