IMO, this feature is almost stable since I fixed most of bugs which occurs
during inline conversion. And now I enable this feature by default when I do the
test with fstest suit and fsstress, I didn't find any more bugs reported by
those test tools.

How do you think of enabling inline_dentry by default now?
