Just wanted to thank everybody for their help.  I ended up backing off
the lofty goals and worked towards just passing fsx for now.  The main
thing needed was an invalidate_inode_pages2(inode->i_mapping) when I
wrote the file through the uncached method (in order to invalidate any
read buffers).  It turns out fsx was msync'ing the mmap writes so that
path was already clear.

I've got plenty of other fires to fight before I go after the more
extreme case, and perhaps direct I/O is the appropriate way to go
about it.

Thanks again.
