Subject: [PATCH, RFC] Clean up of delalloc code and map-on-close/rename fixes

Ok, here are the patches I was talking about at our call today.  They
clean up the delalloc code, and then add an ioctl for forcing delayed
allocation blocks to be allocated.  The last two patches force delayed
allocation blocks to be allocated on close if the file had been
previously truncated, and on rename if the old file is displacing
another file.

I would appreicate some review.

Thanks!!
