Goldwyn Rodrigues 6216277c08 Treat writes as new when holes span across page boundaries ...

commit 272b62c1f0 upstream.

When a hole spans across page boundaries, the next write forces
a read of the block. This could end up reading existing garbage
data from the disk in ocfs2_map_page_blocks. This leads to
non-zero holes. In order to avoid this, mark the writes as new
when the holes span across page boundaries.
