This is version 3 of the ocfs2 tail zeroing fixes. This version has some major changes. Tao correctly pointed out that we can have multiple extents past i_size due to unwritten extents. I've reworked the zeroing code to walk them all. Since I had to do that, and I had to handle refcounted extents, I end up fixing a refcount bug with non-sparse extentds. There are now three patches. The first changes our zeroing code to go page-by-page at the high level. The second actually changes the zeroing code. The final patch, limiting zeroing to the end of a write, is unchanged from v2.
