We could mention here that this patch is going to be replaced by a new
patch to use the fallocate() operations.

I think Amit has an updated version of this patch in his place.

This nanosecond patch could be move to upstream earlier than the delayed
allocation patch (Alex is working to rewrite it at VFS level), so shall
we move it before the booked-page-flag.patch?

I wonder if we should create two branches: one branch for patches that
are well discussed and tested, which Andrew could trust and pull to mm
tree; and create another branch to store patches that are still under
discussion and likely to be rewriten based on the review feedback.
