Update the function in GFS2 which deals with truncation of partial blocks. Some of the code is "borrowed" from ext3 since it appears to give a good model of how to do this operation. The function is renamed gfs2_block_truncate_page accordingly. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
